Question

air, like other gases, flows from a region with higher pressure to a region with lower pressure. muscular breathing movements and recoil of elastic tissues create the changes in pressure that result in the breathing process. which of the following can be inferred from this paragraph? a air is the only gas that humans can safely breathe. b gases generally flow from high pressure areas to low pressure areas. c some people have more muscular breathing movements than others.

Explanation:

The text explicitly states that air, like other gases, flows from a region with higher pressure to a region with lower pressure. Option A is not supported as the text doesn't claim air is the only breathable gas. Option C has no basis in the given paragraph.

Answer:

B. Gases generally flow from high - pressure areas to low - pressure areas.
