LSAT Practice Test

Which one of the following, if true, most helps to explain why raisins contain more iron per calorie than do grapes?

1. Raisins have a higher iron absorption rate due to their drying process

2. Grapes naturally have a higher water content which dilutes the iron concentration

3. Iron-rich soil is typically used to cultivate raisin-producing grapevines

4. Grapes' sugar content interferes with iron absorption in the body

The correct answer is: Raisins have a higher iron absorption rate due to their drying process

Raisins contain more iron per calorie than grapes because the drying process they undergo helps to concentrate the iron present in them. By removing the water content through the drying process, the iron content within the raisins becomes more concentrated, resulting in a higher amount of iron per calorie. This concentration of iron due to the drying process is what makes option A the correct choice. Option B is incorrect because the water content in grapes does not directly influence the iron concentration per calorie between raisins and grapes. Option C is irrelevant as it pertains to the soil quality rather than the iron content comparison. Option D is also off-topic as it discusses the potential interference of sugar content in grapes with iron absorption, which is not related to the concentration of iron in raisins compared to grapes.
