Those who practice cross-training while recovering from feet injury spend more time on their feet than those who do not. Even accounting for disparities in the severity of the injuries, those who practice cross-training heal faster than do those who do not. This is puzzling because an injured body part that is put into regular use typically heals slower than one that is allowed to rest.
Which of the following, if true, best resolves the apparent discrepancy described in the passage?
A. Spending time on their feet increases the patients’ blood flow to feet, causing the injured feet muscles to absorb more of the nutrients needed to heal.
B. Cross-training increases the patients’ confidence, encouraging them to start walking.
C. Increased activity leads to an increased demand for nutrients needed to heal injuries.
D. Cross-training does not increase the recovery rate of middle-aged individuals, if they had not undergone cross-training before.
E. Those recovering from feet injury need more rest than those recovering from other injuries do.

The general picture is there a few people practising cross training and few who do not. Now, they speak about a specific aspect feet injury and recovery amongst the two groups.
People who practise cross training and even if they are seriously injured , get recovered soon compared to those who do not practice cross training.
The puzzling aspect is - if an injured body part is put to regular use, then the time we give for it to heal and recover is minimised. Thus, the healing rate is drastically reduced. But, the paradox here is it heals faster, provided you are practicing cross training.
Which of the following, if true, best resolves the apparent discrepancy described in the passage?
A. Spending time on their feet increases the patients’ blood flow to feet, causing the injured feet muscles to absorb more of the nutrients needed to heal.
This explains the logical gap, frequent usage, increases the blood flow to these places, increasing the nutrients that’s needed for increasing the absorption rate of these nutrients, enabling faster healing and recovery. This is the correct answer.
B. Cross-training increases the patients’ confidence, encouraging them to start walking.
Confidence to walk is different from faster healing and recovery. Hence, out of scope option.
C. Increased activity leads to an increased demand for nutrients needed to heal injuries.
Increased Activity leads to increased demand for nutrients, and these nutrients can be either food, medicines specific to the region or whole body. But, the context is more specific to feet injury and its speedy recovery because of cross training. This option speaks more generalised rather than moving to specifics as option A does. Hence, Wrong.
D. Cross-training does not increase the recovery rate of middle-aged individuals, if they had not undergone cross-training before.
This is another out of scope option, as this speaks about middle aged individuals, while the passage is speaking about those who practise cross training. This option shifts focus from passage generalisation to specifics. Thus, wrong.
E. Those recovering from feet injury need more rest than those recovering from other injuries do.
The context is not about feet injury vs other body part injuries. The comparison is specifically to two groups who have feet injuries, and their recovery - one group practises cross training , while the other group doesn’t. Hence, wrong.
Option A
