Answer: 0


Explanation: At the top of the instrument (the pegbox), there are dark cylindrical pegs protruding horizontally from the sides; these are the tuning pegs and they can be seen distinctly against the white background.

Answer: 0


Explanation: The instrument’s body, fingerboard, bridge, f-holes, pegs, and tailpiece are visible, but there are no discernible lines running from the pegs over the fingerboard/bridge down to the tailpiece. If strings were present, they would appear as thin parallel lines against the bright background and dark fingerboard; they are not seen here.

Answer: 2


Explanation: The instrument is shown from the front, where f-holes would normally appear as two dark, f-shaped cutouts on either side of the bridge. In this image, the top plate looks continuous and smooth with no cutouts or dark openings in those positions, so no f-hole can be seen.

Explanation: The aircraft is shown in a side view, and the tail section is visible. You can make out the vertical fin/rudder rising above the rear fuselage near the end of the horizontal stabilizer, but it appears small and blends into the background, making it not very prominent.

Answer: 1


Explanation: The aircraft is shown from a side angle, so only the near-side cockpit/cabin windows are visible. Any windows on the far side are hidden by the fuselage and cannot be seen in this view, so not all windows are visible.

Answer: 2


Explanation: The bike shows a seatpost and clamp, but there is no saddle/seat mounted on top—only the bare seatpost is visible.

Answer: 2


Explanation: The aircraft is shown from the side with the tail section visible on the left. The vertical fin/rudder is clear, and a small portion of the horizontal tailplane (horizontal stabilizer) can be seen extending from the base of the fin, though it blends with the white fuselage and is partially obscured by the viewing angle.

Answer: 1


Explanation: The bike shows the front fork and a vertical steering tube/stem area, but there is no horizontal bar or grips extending left and right that would indicate a handlebar.

Answer: 2


Explanation: The aircraft is shown from the side with the wings visible, and jet engines would be mounted beneath the wings. In this image, a dark engine nacelle is present under the wing, but it blends into the shadowed underside and is partially obscured, making it not very distinct at a glance.

Answer: 1


Explanation: The aircraft is shown from the side, and while the horizontal stabilizers (tailplanes) are visible at the rear, there is no distinct upright tail fin rising above the fuselage that would indicate the vertical stabilizer. The rear outline appears to show only the fuselage and horizontal surfaces.

Answer: 2


Explanation: The aircraft is shown in a side view, and at the rear tail section you can make out a small horizontal surface extending from the fuselage just ahead of the vertical tail fin. It’s present but not very prominent due to the angle and lighting, so it doesn’t stand out strongly.

Answer: 1


Explanation: Looking at the drivetrain area (where pedals would be attached to the crank arms near the chain), there are no pedal bodies or crank arms clearly shown. The chain and rear components are visible, but the pedals themselves do not appear in the image (likely hidden or not present in this view).

Answer: 2


Explanation: The aircraft is shown from the side, and near the front (nose) there is a small, darker set of shapes where the cockpit windows are located. However, because the plane is at some distance and the window details are small, the cockpit windows are not very distinct.

Answer: 1


Explanation: The image shows the back of an Apple device with the logo centered. A camera lens would typically appear as a small circular glass element near a corner, but no such lens or camera module is visible anywhere on the device surface in this photo.

Answer: 2


Explanation: The image shows the back of an iPad at an angle. The visible edges do not show any perforated grille pattern; the only small openings visible are the camera and a tiny microphone/port near it, not speaker holes (which are typically a row of holes on the bottom/side edge).

Answer: 0


Explanation: Looking at the top-left corner of the keyboard, the first visible key is the tilde/backtick (`~) key, and there is no separate key labeled “Esc” above or to the left of it in the image. Therefore, the Esc key is not shown.

Answer: 2


Explanation: The keyboard area is visible, including the top-left corner where the Esc key normally sits. However, the image resolution/angle makes the key label itself difficult to clearly read, so it’s present but not distinctly identifiable by text.

Answer: 1


Explanation: The visible edge of the phone shows a central charging port and rows of small speaker/microphone holes, but there is no round 3.5mm headphone jack opening visible anywhere in the image (the edge where it would appear is not shown with a jack).

Explanation: On the right side of the door there is a vertical metal pull handle with a dark grip area, and it is unobstructed and easy to see.

Answer: 0


Explanation: The image shows the underside of an airplane against a very bright, washed-out sky. While the wings and fuselage are clear, there are no distinct engine nacelles (the usual pod-shaped structures under the wings) that can be confidently seen due to the angle/contrast and lack of visible engine outlines.

Answer: 2


Explanation: The visible side of the device only shows small pinholes/indicator openings; there is no rectangular or oval charging connector opening (e.g., Lightning/USB-C) shown in the image.

Answer: 2
