You're looking for what would strengthen the argument. One way to strengthen the argument is to eliminate another possible explanation. That's what answer B does, so it strengthens. E does not strengthen the argument, because it does not state a fact. It only states that the scientists think that so...

The author is saying that the truth is the surest weapon in our fight against our foes. If this is true, then the disinformation campaigns will not always help us, as stated in E. Here's a look at the remaining answers: A-The author makes no argument that is based in morality. B-The author does not ...

B indicates that the readings will be more accurate, but there's no reason to expect that they would go up or down. So it doesn't help explain the change. D indicates that the law, prior to 1988, was not being enforced. If this is combined with the assumption that the law was enforced after the Mayo...

I believe that A is the correct answer. The conclusion of the argument is that any star containing no lithium is not one of the coolest brown dwarf. The evidence for the conclusion is that brown dwarfs do not burn hot enough to destroy lithium, and that all other stars do. The assumption is that the...

For the first argument, you're looking at a favorite reasoning flaw on the GMAT: Sampling and Statistics. The error they love to throw in is the false assumption that %'s = #'s. In other words, just because the pharma div.'s % of the profits went up doesn't mean that they made more money. That's pre...

For the first question, I assume the answer is A? B says "weights as much as a penny", which is not a proper verb.

For the second, there are a lot of errors in the modifying phrase about Ben Franklin. You need "not only/but also" here, and you don't need he was. I assume the answer is B?

Plug in numbers here. For statement 1, let's say that c=2 and d=2. These are acceptable numbers, since the make c(d+1)=2(2+1)=6, which is even. And for these numbers, c is even. But you could also have c=1 and d=1, since 1(1+1)=2, which is even, so those values satisfy the statement. (When you're pl...

Counting each way is perfectly acceptable. I don't know how comfortable you are with the math, but for if you're a mid-scoring student I would probably tell you to count 'em up. To get there in the shortest route, Pat has to go right two and up three. Let's call those RR and UUU. Since there are 5 m...

For the first one I'd also vote for D. It's the only one that might help their case for the machine. The fact that shades change over the growing system doesn't really help much; the important consideration is whether the machine can accurately tell the difference between all crops and all weeds. If...

The conclusion of the argument is that there is no significant health benefit from administering the nasal vaccine to kids. The evidence offered is that kids are not at risk from serious complications. The argument is assuming that this is the only problem that could be addressed by the vaccine. D p...

That's certainly how to get there algebraicaly. The key thing to remember on Data Sufficiency is that we don't always need to be able to actually solve, we just need to know when we could solve.

Often on DS picking #'s can help you make sense of the statements. On DS questions that ask you a yes/no question, you have to remember that the statment is only sufficient if it gives you always yes or always no, not both. For statment 1, let's say x=2, q=2, and p=2. that gives us (2+2)(2+2)=4*4=16...

Well, the arc length that they give us is for major arc XYZ, if I'm reading the problem correctly. Since the angle for minor arc XZ would be 120, then the remaining angle for major arc XYZ would be 240. So 240/360 = 18/Circumference, so the circumference would be 27.

Could you post part of the explanation and tell us what's confusing to you? That will help answer your question.
