Explanation:

Question 1

When an object cools, its temperature decreases. "Rises" and "goes higher" mean temperature increases, and "stays the same" is incorrect. So the correct answer is B.

Option A is wrong as thermometers vary. Option B is about early thermometers' making, not the third paragraph's main idea. Option D is about reading, not the focus. The third paragraph likely explains how one type of thermometer (like bulb - type) works. So the answer is C.

A bulb thermometer's tube is hollow to allow the liquid to expand/contract. "Huge" is not typical, "hot" is not a defining feature of the tube, and "white" is not a characteristic of the tube's structure. So the answer is B.

Answer:

B falls
