Which one of the following can be inferred from the passage about pumps that are currently available to boost the nat...

Hello, Doesn't B get lines 23-to-29 backward? B states: "These pumps are more efficient when the crude is less subject to sudden increases in the proportion of gas to liquid." I call your attention to the phrase "increases in the proportion of gas to liquid." Doesn't this phrase mean that gas in being converted to liquid? Doesn't B mean gas-to-liquid? It should have said liquid-to-gas, because the question is "less subject to." My initial gut was A is too strong. But B gets it backward! When we refer to the lines 23 to 30, clearly the increases are in the proportions of gas that are causing the reduction in pressure/head. 60% liquid is being converted to 70% gas which is having the effect of the "loss of pressure." Please please please respond. This important! "increases of proportions" of A-to-B should not mean both A-to-B and also mean B-to-A! What am I missing? Thank you
