Explanation:

First Question (4 points)

We analyze each option:

• "Hard Lens": A convex lens used for magnification matches the description of a lens (maybe a typo for "Hand Lens" or a specific lens type for magnification).
• "Camera": Cameras use lenses but the description here is more about a lens for magnification (not the camera as a whole).
• "Gloves": Not related to lenses or magnification.
• "Thermometer": Measures temperature, not related.
• "Computer": Processes data, not related to lenses for magnification.

So the correct option is the one related to a convex lens for magnification, which is "Hard Lens" (assuming it's a lens for magnification, maybe a hand lens typo).

We analyze each option:

• "Camera": Cameras (especially pinhole cameras or traditional cameras) are sealed boxes with a small hole (or lens) to let light in and capture images on a light - sensitive surface (like film or a sensor).
• "Clock": Measures time, not related.
• "Gloves": Protective gear, not related.
• "Hard Lens": A lens, not a sealed box with a hole for image capture.
• "Ruler": Measures length, not related.

So the correct option is "Camera".

Answer:

Hard Lens (the option with "Hard Lens" text)
