Mechanicorp’s newest product costs so little to make
that it appears doubtful the company will be able to
sell it without increasing the markup the company
usually allows for profit: potential clients would
simply not believe that something so inexpensive
would really work. Yet Mechanicorp’s reputation is
built on fair prices incorporating only modest profit
margins.

The statements above, if true, most strongly support
which of the following?
(A) Mechanicorp will encounter difficulties in trying
to set a price for its newest product that will
promote sales without threatening to compromise
the company’s reputation.
(B) Mechanicorp achieves large annual profits, despite
small profits per unit sold, by means of a high
volume of sales.
(C) Mechanicorp made a significant computational
error in calculating the production costs for its
newest product.
(D) Mechanicorp’s newest product is intended to
perform tasks that can be performed by other
devices costing less to manufacture.
(E) Mechanicorp’s production processes are designed
with the same ingenuity as are the products
that the company makes.

I am trying to understand how to distinguish between a must be true and strengthen question. If the above question is must be true then the ans makes sense. Can some one please clarify this doubt for me. I am confused.

You are correct, the above question is a "must-be-true," question, or an Inference question. It is NOT a Strengthener.

How to tell the difference? Many GMAT test-takers are confused on this because they focus on the word "support" in the question stem. Here are the two question stems to differentiate between:

i. The statements above, if true, support which of the following?
ii. Which of the following, if true, supports the argument above?

Now, the big clue in how I worded it is that only (ii) refers to an Argument. And that's the biggest difference for you to be aware of, too: Strengtheners are always about Arguments, and the answer will hinge upon correctly identifying the Conclusion and Evidence and deducing the Assumption from that. Inference questions, such as (i), may not refer to an Argument at all and may simply be based upon a set of Statements, that is, Evidence without a Conclusion, from which you must make a "must-be-true" deduction.

However, it's also worth noting the difference in word order that has logical significance. In (i), the Inference question, we're assuming that that STIMULUS is true -- we would never do this in a Strengthener question, as we're trying to strengthen an otherwise-specious Argument -- and using it to examine the ANSWERS, only one of which "must be true." In (ii), the Strengthener question, we're assuming the ANSWERS are all true, and seeing how each of them affects the STIMULUS differently.

So, to put it really simply: Inference or "must-be-true" questions will look like (i) above: they work down, with the Stimulus taken as true and used to affect the Answer Choices. Strengtheners, which refer to Arguments, take the form of (ii) above: they work up, so that you take the Answer Choices as true and apply to them to the Stimulus in question.

Hope that helps!

For those who seek explaination , Here,s mine. :wink:

After reading the stimulus, you must recognize that it is a MUST BE TRUE question. Hint: question stem states- If above statements are TRUE and NO CONCLUSION. Now, moving forward to answer choices.

(A) Mechanicorp will encounter difficulties in trying to set a price for its newest product that will promote sales without threatening to compromise
the company’s reputation.
Looks promising..Keep it as a contender and move on.

(B) Mechanicorp achieves large annual profits, despite small profits per unit sold, by means of a high volume of sales.
Eliminate: Nowhere in the stimulus does the author makes any point of the PROFITS per unit sold. New info..Eliminate

(C) Mechanicorp made a significant computational error in calculating the production costs for its newest product.
Eliminate: New info again:: Computational error.

(D) Mechanicorp’s newest product is intended to perform tasks that can be performed by other devices costing less to manufacture.
Eliminate: New info again:: Other devices.

(E) Mechanicorp’s production processes are designed with the same ingenuity as are the products that the company makes.
Eliminate: Processes designed with same ingenuity is not the point of the argument. Again new info.

As always, suggestions are welcomed.

Thanks

To identify Must Be True type your first hint will be the question.
Here are some types:
If the statements above are true, which of the following must be true?
Which of the following can be inferred from the passage?
"..most strongly supports which of the following?"
"..which can be drawn as a conclusion.."


Your stimulus (Argument) is taken for granted and you will need to find an answer from a set of suspicious choices (except for one).
Strengthen, on the other hand, will ask you to find support from the answer choices to a stimulus that is weak (either has a gap or error in reasoning, etc).

Once you identify the question then your job is to figure out what answer types are associated with that question type. For Must Be True question, you should find one of two types :
(a) Paraphrased stimulus or part of it.
(b) Answers that are the sum of two more or more stimulus. [Any answer choice that would result from combining two or more statements
in the stimulus will be correct]

Remember that the correct answer in Must Be True can always be proven by referring to the facts stated in the stimulus.

I hope this helps and good luck.
