Question

Raisins are made by drying grapes in the sun. Although some of the sugar in the grapes is caramelized in the process, nothing is added. Moreover, the only thing removed from the grapes is the water that evaporates during the drying, and water contains no calories or nutrients. The fact that raisins contain more iron per food calorie than grapes do is thus puzzling.

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

(A) Since grapes are bigger than raisins, it takes several bunches of grapes to provide the same amount of iron as a handful of raisins does.

(B) Caramelized sugar cannot be digested, so its calories do not count toward the food calorie content of raisins.

(C) The body can absorb iron and other nutrients more quickly from grapes than from raisins because of the relatively high water content of grapes.

(D) Raisins, but not grapes, are available year-round, so many people get a greater share of their yearly iron intake from raisins than from grapes.

(E) Raisins are often eaten in combination with other iron-containing foods, while grapes are usually eaten by themselves.

I think (B) lowers the number of calories, it doesn't "hide" the iron - the amount of iron actually stays the same. Let me explain the question.

The discrepancy that needs to be resolved in this question is that raisins have more iron per calorie than grapes even though the only differences between raisins and grapes are that raisins have less water (which is calorie and nutrient free) and as grapes turn into raisins, some of the sugar is caramelized. We'd expect that the iron per calorie stays the same because it seems that the number of calories and the amount of iron in a grape and it's future raisin-self would be the same.

The only ways to explain this discrepancy are: 1) show that some iron gets added; or 2) show that some calories are lost.

(B) capitalizes on the second option. The caramelization ends up reducing the number of calories, so while the iron amount remains the same, the ratio of iron to calories changes.

(A) compares the number of bunches needed of each to provide a certain amount of iron - where are the calories?

(C) is out of scope as it focuses on absorption rates.

(D) is out of scope - availability?

(E) is out of scope - other foods?

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

(A) Since grapes are bigger than raisins, it takes several bunches of grapes to provide the same amount of iron as a handful of raisins does............. this repeats the fact that raisins contain more iron but does not explain why?

(B) Caramelized sugar cannot be digested, so its calories do not count toward the food calorie content of raisins......... This explains that since food calorie is reduced in the ratio of iron to food calorie the ratio value increases and thus raisins have more ion per food than grapes.

(C) The body can absorb iron and other nutrients more quickly from grapes than from raisins because of the relatively high water content of grapes............... How body absorbs is not of concern here. OFS

(D) Raisins, but not grapes, are available year-round, so many people get a greater share of their yearly iron intake from raisins than from grapes................ why they contain more iron is the question not how much they are available

(E) Raisins are often eaten in combination with other iron-containing foods, while grapes are usually eaten by themselves................ how they are consumed are out of concern and does not explain anything.

OFFICIAL EXPLANATION The paradox in the stimulus is that raisins contain more iron per calorie than grapes even though the two are almost identical in composition. But there is a difference: “some of the sugar in grapes is caramelized” as the grapes are dried in the sun. Since this is the only stated difference between the two that could affect the calorie count (water has no calories), you should focus on an answer that discusses this difference. Answer choice (A): This answer essentially states that grapes are bigger than raisins, and you need several bunches to equal a handful of raisins. The issue is not the size of the grapes or raisins! Answer choice (B): This is the correct answer. If the iron content in the raisins and grapes is identical, but raisins have fewer calories for counting purposes, then the iron per calorie will be higher for raisins, as highlighted by the following example: https://gmatclub.com/forum/download/file.php?id=61088 Note that the paradox could have addressed any common element between raisins and grapes (such as fiber or fat), and raisins would always have the higher per calorie content since they contain fewer countable calories. Answer choice (C): The paradox in the stimulus does not involve the rate at which the body can absorb iron or any other nutrient. This answer misses the point and is incorrect. Answer choice (D): The availability of raisins and grapes is not an issue in the stimulus. The answer then discusses iron, but the point made about yearly intake is irrelevant. Answer choice (E): The comparison in the stimulus is between grapes and raisins. This answer, which brings in other food items, is irrelevant. 2021-03-29_04-13-18.png

B! Phrased another way, 1 raisin will have fewer calories than 1 grape since caramelized sugars aren't digested (bull ****, but assumed). While the iron amount remains the same, the iron amount PER CALORIE is obviously higher for 1 raisin, since it has less calories.

spetznaz · Answer

The argument says that Iron per calorie from resins is greater than that from grapes. 
Iron/calorie --> This fraction will come down for a fixed value of Iron content if total calorie is down. Only option B fits the bill

+1 for option B
