Which of the following conclusions is supported by the data?
Objects A and B will fall at the same rate.
The greater the mass of an object, the faster it will fall.
The time of fall is independent of the mass of the object.
Air resistance is greater for A than for B.
The Correct Answer is C
The data in the table does not support any of the conclusions a, b or d. The only conclusion that can be drawn from the data is c. The time of fall is independent of the mass of the object. This is because objects 1 and 2 have the same mass but different times of fall, while objects 3 and 4 have different masses but also different times of fall.
A. Objects A and B are not mentioned in the table, so this conclusion cannot be drawn from the data.
B. The data does not support the conclusion that the greater the mass of an object, the faster it will fall. In fact, object 3 has a greater mass than object 2 but falls in less time.
C. Air resistance is not mentioned in the table, so this conclusion cannot be drawn from the data.

Correct Answer is B
Explanation
Emphysema is a lung condition that is caused by damage to the alveoli, the tiny air sacs in the lungs where gas exchange occurs. When the alveoli are damaged, the body has difficulty exchanging oxygen and carbon dioxide. This can lead to shortness of breath and other respiratory problems. The other options are not directly related to the function of the alveoli or the effects of emphysema.
