The correct answer is
C.
Let's understand the argument first.
Conclusion:
Quote:
A
well-balanced meal with different types of food is a better source of vitamins than
energy bars alone.
We need evidence that makes this conclusion
more believable.
A.
Quote:
People who eat energy bars often neglect natural vitamin-containing foods.
This tells us that energy-bar users may
replace healthy foods with bars.
It somewhat supports the argument, but it doesn't prove that the
vitamins in the bars are inferior.
B.
Quote:
Energy bars with supplements are as easy to digest as bars without supplements.
This is about
digestion, not whether they are a better source of vitamins.
No meaningful support.
C.
CorrectQuote:
Natural vitamins combined with other nutrients are
more usable by the body than the vitamin supplements in energy bars.
This directly explains
why a balanced meal is a better source of vitamins.
Even if the energy bar gives you
100% of the recommended amount, your body may be able to use the vitamins from natural foods more effectively.
So:
Balanced food → vitamins more usable → better vitamin source\boxed{\text{Balanced food → vitamins more usable → better vitamin source}}
This is
direct support for the conclusion.
D.
Quote:
Few balanced meals provide 100% of the recommended daily vitamin amounts.
This actually
weakens the argument.
If balanced meals usually don't provide 100%, while energy bars can provide 100%, that makes energy bars look
better, not worse.
E.
Quote:
Energy bars come in different flavors and sizes.
Completely irrelevant to whether they're a better source of vitamins.
Answer:
CGMAT trick: When the conclusion says
"X is better than Y," look for an answer that explains
why X provides a meaningful advantage over Y.
Here,
C directly gives us that advantage: the body can use vitamins from natural foods more effectively.

Many energy bars contain vitamin supplements. Some of these bars provide 100% of the recommended daily vitamin consumption amounts. Nevertheless, a well-balanced meal, including a variety of food types, is a better source of vitamins than eating energy bars alone.
Which of the following, if true, would most strongly support the position above?
A. People who regularly eat energy bars that contain vitamin supplements often neglect to eat foods that contain these vitamins naturally.
B. Energy bars that contain vitamin supplements are as easy to digest as similar energy bars that do not contain vitamin supplements.
C. In many kinds of foods, the natural combination of vitamins with other nutrients results in these vitamins' higher usability to the body than the vitamin supplements that energy bars contain.
D. Few meals, as balanced and varied as they may be, provide the body with 100% of the recommended daily vitamin consumption amounts.
E. Energy bars containing vitamin supplements come in a variety of flavors and sizes.
