D..

D. i think it is strngthen question. the answer Corroborates the conclusion of the argument.

I got D in this one.

gmataquaguy, what's the OA?

A strengthen question and answer is D since the excess carbs
by-products are stored as fat

I will go with A.
D sounds too generic. The author no where has mentioned anything about people on diet. A talks about the people who think simple carbohydrates as a replacement for low fat. This is within scope of the argument.

But the question(misleading) is not concerned with the scope of argument then D may be true.

For those of you who chose AC D was the OA crystal clear? Here is what i was thinking, when i chose A and eliminated AC D.

For A: If you are on a low fat diet and consume/replace low fat diet with "simple carbs" then the following happens:
- You'll produce more insulin and therefore your body uses the insulin to a) increase or energy level or b) when energy is not required more fat is produced.
In BOTH conditions a) or b) your energy level ISNT the same as what it was prior to the switch. THat is what AC A is saying. So what gives?

For D: Isnt it possible that condition "a" occurs for people who switch to the simple carb diet and therefore the should in AC D isnt really applicable?

Pls elaborate......

Okay. Would you care to elaborate on some of posted questions?

Hello gmataquaguy,

You had asked me to explain why I chose D. D was a natural pick, and I will explain my reasoning.

Before proceeding to pick an answer choice that most strongly supports the author's argument, quickly summarize the arguments in two lines.

The nutritionist says that - People claim that simple carbohydrates are a good alternative to low fat diets, but the truth is simple carbs, can turn into fat, when energy is not required. So, we can conclude from the author's argument that simple carbohydrates can turn into fat, and people who take low fat diets to avoid weight gain, should refrain from simple carbohydrate.

Once you have understood, what the nutritionist is trying to convey, you can check the answer choices.

Choice A is intended to trap test takers. It uses key words, "low fat diets", "avoid..simple carbs","energy level". But taken together, choice A conveys a totally different meaning. The nutritionist is definitely not saying that people on low fat diets should avoid simple carbs to maintain their energy level that their body require. The word energy level is meant to mislead you. From the conclusion we arrived earlier, we know that the nutritionist was cautioning people who wanted to avoid weight gain from taking simple carbs, as simple carbs can lead to weight gain. Therefore A is out.

Again from our conclusion, we know that D is true.

Regarding your question about question types.
I have classified CPA (Conclusion - Premise - Assumption) question types as follows :-

1. Weaken questions
2. Strengthen Questions
3. Flaw questions
4. Assumption questions
5. Evaluate questions
6. Support questions

The best way to resolve a support question is to first condense the author's argument in your own words, and then find the answer choice that most strongly agrees with your summary or conclusion

Hope this helps
