Answer: 0


Explanation: Looking at the electric kettle image, the handle is clearly visible on the right side. A spout would typically be located on the opposite side (left side) or the front of the kettle for pouring water. Examining the image carefully, the kettle shows a smooth stainless steel body with a black lid on top and a black base. While viewing the kettle from a 3/4 angle that shows the handle side and front, there is no visible pouring spout or lip apparent in the photograph. The left side of the kettle (opposite the handle) appears smooth and curved without any protruding spout structure that can be seen from this camera angle.

Answer: 2


Explanation: Looking at the shopping cart image, I can identify wheels at the bottom of the cart. Specifically, there is a green wheel visible near the back right corner and a silver/metal wheel visible at the front left area of the cart's base. These wheels, while not the largest elements in the image, are clearly discernible and not obscured by any other parts of the cart.

However, the squeeze lever (also called the operating lever or discharge handle) - the specific lever that is squeezed to activate the extinguisher - is not visible in this image. While the valve assembly and pressure gauge are visible at the top, the squeeze handle mechanism that is typically found adjacent to the carrying handle is either positioned on the opposite side of the valve or obscured by the viewing angle of the photograph.

Answer: 2


Answer: 2

Explanation: The image shows a Cessna aircraft from a side view angle. While the nose of the aircraft is visible on the right side of the image, there is no propeller visible at the front of the aircraft. The propeller would typically be mounted on the nose of this type of single-engine aircraft, but in this particular photograph, the propeller blades are not visible - either due to the angle, lighting, positioning of the blades, or other factors. The nose cone is visible, but no propeller blades extend from it that can be seen in this image.


Explanation: The aircraft has windows on both the visible side and the opposite side. While the windows on the side facing the camera (left side) are visible as dark tinted areas, the windows on the far side (right side) of the aircraft are completely obscured by the fuselage and cannot be seen from this angle. Since the question asks if ALL windows are visible, and the windows on the opposite side are not visible, the answer is that not all windows are visible in the image.

While it is technically present and can be identified upon close inspection, it is not prominent or immediately obvious at first glance.

Answer: 1


Answer: 2

Explanation: The image shows the back of a silver iPad against a peach/orange background. While examining the back panel carefully, I can see the 'iPad' text branding at the bottom center, but the Apple logo (which is typically located in the center of the back panel on iPad devices) is not visible in this image. The silver Apple logo blends in with the silver aluminum body, and due to the lighting conditions and angle of the photograph, there is insufficient contrast to distinguish the logo from the rest of the back surface. The back appears as a uniform silver color with only the 'iPad' text clearly visible at the bottom.


Explanation: The image shows the back of a light green iPhone being held in a hand. Looking at the back of the phone, I can see only the Apple logo in the center.

Explanation: Looking at the front of the Amtrak locomotive #146, the driver cab is located at the front of the train. The cab windows (windshields) are present on the front blue section of the locomotive, but they are heavily tinted and blend in with the blue paint color. While the front of the train is clearly visible in the image, the cab windows are not immediately obvious or easy to distinguish - they appear as darker areas on the blue front that require close inspection to identify. They are not 'clearly visible' (option 0) because they blend with the blue color, but they are technically present in the image and can be seen upon careful examination, so they are not 'not visible' (option 2).

Answer: 1


Explanation: The aircraft in the image is a commercial jet (appears to be an Airbus A320 family aircraft) with engines typically mounted under the wings. From the viewing angle - looking up at the belly of the plane from a front-below perspective - the engine nacelles are technically present under the wings. However, they are partially obscured by shadows and blend in with the dark underside of the aircraft and wing structure. The landing gear is prominently visible and draws attention, while the engines are much less distinct and require careful observation to identify. They are not clearly visible like the landing gear or fuselage, but can be discerned upon close inspection of the area beneath the wings near the fuselage.

Answer: 1

Explanation: After carefully examining the sink basin in the image, including the interior walls, rim, and all visible surfaces, there is no overflow hole present. The sink shows a smooth white basin with only the main drain visible at the bottom center. No secondary overflow opening can be observed on any of the basin walls or near the rim.

Answer: 2


Explanation: Looking at the image, this appears to be the bottom of a MacBook Pro laptop placed on a wooden table. I can see the bottom case with the 'MacBook Pro' text, several screws around the perimeter, and ports visible along one edge. MacBook Pros typically have four rubber feet at the corners of the bottom case. However, examining the image carefully, I can identify screws at various positions, but I cannot see any distinct rubber feet. The bottom surface appears to be a smooth metal/plastic surface without the characteristic rubber pads that would be visible as separate, slightly raised circular or oval features at the corners. The rubber feet are either not present, worn off, or not visible from this angle and lighting.

Answer: 2


Explanation: The touchpad (trackpad) is located on the palm rest area of the laptop, positioned below the keyboard. While the touchpad is physically present in the image and occupies a visible portion of the laptop's surface, it blends in with the dark color of the laptop body (which appears to be Space Gray or Midnight). The boundaries of the touchpad are difficult to distinguish clearly because there is low contrast between the touchpad surface and the surrounding palm rest area. The touchpad is visible upon close inspection, but it is not prominently distinct or clearly outlined.

Answer: 1


Explanation: Looking at the electrical outlet plate in the image, I need to check for the presence of a mounting screw. Standard outlet plates typically have a screw in the center to secure them to the wall. Examining the image carefully, the white outlet plate is mounted at an angle (diamond orientation) on a light gray wall. The center area of the plate, where a screw would normally be located between the two socket outlets, appears smooth and flush. There is no visible screw head in the center or at any other point on the plate. The plate surface is uniform white without any visible fasteners.

Answer: 2


Explanation: The image shows the bottom edge of an iPhone (appears to be iPhone 6/6S model). The visible components are: the 3.5mm headphone jack on the left, a small microphone hole next to it, the Lightning charging port in the center, and two screws flanking the Lightning port. On this iPhone model, the speaker grille is located on the right side of the Lightning port and consists of a series of small holes. However, in this image, the speaker grille is not visible - the image is focused on the left-center portion of the bottom edge, and the right side where the speaker would be located is either cut off from view or not shown clearly enough to identify the speaker holes. The small hole visible next to the headphone jack is the microphone, not the speaker.

Answer: 2


Explanation: The image shows a standard North American duplex electrical outlet (NEMA 5-15 or 5-20). Each socket has three openings: two slots for the hot and neutral connections, and a D-shaped or semi-circular hole at the bottom for the ground pin. In both the upper and lower sockets, the ground pin hole is clearly visible beneath the two vertical/horizontal slots. The holes are not obscured by shadows or angle, and their distinct semi-circular shape can be seen in the photograph.

Answer: 0


Explanation: Looking at the image, I can see a Dell monitor displaying a login screen for UBC Okanagan Campus. At the bottom of the screen, there is a Windows taskbar visible with a Search box in the center and system tray icons on the right. However, examining the left side of the taskbar where the Windows Start button (Windows logo icon) would typically be located, I do not see it present. The taskbar shows the Search box and various application icons, but the Windows Start button is not visible on this login/lock screen interface.

Answer: 2


Explanation: The image presents a direct head-on view of an aircraft on final approach. Cockpit windows are positioned on the forward upper fuselage and are angled downward and forward to allow pilots visibility during flight. From this frontal perspective (especially viewing from slightly below the aircraft's flight path), the cockpit windows are obscured by the curvature of the nose section. The white nose cone visible in the image does not show any distinct window patterns or dark areas where the cockpit windows would be. The angle of view makes it impossible to see the angled cockpit glazing from this position.

Answer: 2


Explanation: The image shows a Triumph motorcycle positioned at an angle, with the front of the bike facing to the right. The handlebar is typically located at the front of the motorcycle, attached to the fork that holds the front wheel. In this image, the front fork and other components around the handlebar are visible, but the handlebar itself is not visible because it is likely obscured by the front fork and the headlight assembly. Therefore, we need to determine if the handlebar is visible or not based on the parts of the motorcycle that are visible.

Answer: 2


Explanation: The image shows a USB-C to Lightning cable. The USB connector is not visible as the end that is connected to the charger block is obscured. The Lightning connector, meant for an iPhone or other Apple device, is visible.

Answer: 2


Explanation: The image shows a USB charger, but the USB connector itself is not visible. Instead, the focus is on the power adapter and cord. Therefore, the USB connector is not visible.

Answer: 2


Explanation: The image displays a charging adapter and a cable. One end of the cable is a USB-C connector, which is inserted into the charging adapter. This connector is clearly visible at the connection point, identifiable by its rectangular shape and metallic contacts, unlike the Lightning connector at the other end.

Answer: 0


Explanation: The image shows a charging cable with an AC plug (likely a USB wall adapter) at one end and a white-tipped connector at the other end. The white-tipped connector appears to be a Lightning or USB-C connector, which falls under the umbrella of USB connectors. Therefore, a USB connector is indeed visible.

Answer: 0


Explanation: The image displays a charging block with standard AC wall prongs and a purple cable. One end of the cable is plugged into the charging block, hiding any connector that might be there. The other, loose end of the cable features a visible connector. Upon close inspection, this connector is a solid, flat, rounded piece of metal with external electrical contacts, which is characteristic of an Apple Lightning connector, not any type of USB connector. Therefore, there is no USB connector visible.

Answer: 2


Explanation: The image shows a power adapter with standard wall plug prongs on one side and a cable attached to the other side. The free end of the cable terminates in a smooth, solid white cylinder. This cylindrical end does not have the characteristic shape, metal shielding, or visible pins of any standard USB connector (such as USB-A, USB-C, or micro-USB). Furthermore, the cable appears to be permanently affixed to the charging block rather than plugged into a USB port. Since no USB plug or port is shown, there is no USB connector visible.

Answer: 2


Explanation: The image shows a charging adapter with a power plug and a cable ending in a connector. The connector visible appears to be a lightning or proprietary type rather than a USB connector.

Answer: 2


Explanation:
The image shows an electrical plug with a purple braided cable attached. The end of the cable is visible, but it appears to be rounded and capped, not resembling a standard USB connector, which typically has a distinct rectangular shape. Hence, the USB connector is not visible.

Based on the available visual information, the USB connector cannot be seen in this image.

Answer: 2


Explanation: The image shows a purple/lavender colored charging cable with a Lightning connector (Apple's proprietary connector) visible at the top right of the image. However, the question asks specifically about a USB connector. The cable shown has a Lightning connector on one end (visible) and the other end is connected directly to the wall adapter block - there is no standard USB-A or USB-C connector clearly visible as a separate connector end. The adapter block itself may have a built-in connection, but no traditional USB connector is distinctly visible as a plug end. The Lightning connector is visible, but that's not a USB connector per se. There is no clearly visible USB connector in this image.

Answer: 2


Explanation: The image shows a phone charger (充电器) with a purple braided cable. Looking at the connector end of the cable (the white tip at the top right), it appears to be a USB connector - likely a Lightning or USB-C connector. The connector end is visible but it's somewhat small and the exact type is a bit difficult to determine clearly due to the angle and size. However, a connector is clearly present and visible at the end of the cable.

Answer: 0

Answer: 2


Explanation: In the image, the charger includes a cable with a connector at its end. This connector (the white-tipped end of the cable) is clearly visible and appears to be a USB connector (consistent with typical charging cable designs).

Answer: 0


Explanation: The image shows a purple charging brick and a braided cable. The charging brick has an integrated US-style power plug, and the charging cable terminates in a Lightning connector for mobile devices. The connection point where the cable enters the brick is hardwired or enclosed in a way that the USB-A or USB-C male/female connector interface is not visible. Though a USB connection likely exists structurally inside the plug or at the interface, no standard USB connector is visible in the frame.

Answer: 2


Explanation: The image shows a wall charger, a cable, and a connector tip. However, the specific USB interface (like USB-A or USB-C plug that would typically plug into the adapter) is not visible because the cable appears to be permanently integrated or the connecting end is hidden behind the adapter housing. Additionally, the power plug part has two standard AC prongs, not a USB connector.

Answer: 2


Explanation: The image shows a charger with a cord that has a USB-C connector on one end. The connector is clearly visible as it is not blocked by any other objects in the image.

Answer: 0


Explanation: The image shows a charger with a cord and a plug. The cord is coiled and has a yellow label around it. At the end of the cord, there is a white connector visible, which appears to be a USB connector. Therefore, it is clearly visible in the image.

Answer: 0


Explanation: The image shows a wall charger with a cable attached. The cable ends with a Lightning connector (Apple's proprietary connector for iPhone/iPad), which is not a USB connector. There are no USB-A, USB-B, or USB-C connectors visible anywhere in the image.

Answer: 2


Explanation: Looking at the image, there is a charging cable with a white tip/connector visible at the top right of the image. However, the connector is relatively small in the frame and appears to either have a protective cap on it or the specific details (metal contacts, exact connector type) are not clearly distinguishable. While the white housing or cap is visible, the actual USB connector interface is not clearly identifiable.
