The Census Bureau predicts that within the next ten years a

good question ..got it wrong choose C.

We can not use future tense here since we know time horizon - within next ten years. Only D is correct and concise

The 'will' is not to be underlined; That is a typo; All choices including D have to be read with 'will'; yes D makes sensse in using a future tense for a prediction that is going to happen in the next 10 years.

Could anyone please explain why option A is incorrect?

Hi eybrj2,

Since you are asking about a specific answer, let's compare C to the correct answer D:

C. have left corporate job to start their own businesses, as did many Black engineers and computer experts already.

When saying "as did," it suggests that Black engineers and computer experts left their jobs in the past, but aren't still leaving them today. This keeps the action solely in the past, which isn't true - these people will continue to leave their jobs over the next 10 years too - they just started doing so sooner.

D. leave corporate job to start their own businesses, as many Black engineers and computer experts have done already.

When saying "have done," it means that the action started in the past, and it continues to happen now (or into the future). Therefore, this is the better answer to show when and how long the action takes place.

between D and E, "so as to" is incorrect here.
"have done" and "have left" are all fine.

What is the difference in meaning between "will have left" and "will leave"?
I narrowed it down to (C) and (D) and thought "will leave" was the better choice and selected (D).
Not 100% sure about the meaning.

Hi CrackVerbal,

Hello lary301254M7,

I will be happy to help you with this one.

Will have left is a future perfect tense verb. This verb tense is used to refer to an action that is expected to take place before a particular time in the future. For exampe:

I will have finished my project by end of this month.


Will leave is simple future tense verb. This verb tense is used to present an event that will take place in the future. For example:

I will finish my project tomorrow.


Now let's see usage of which verb tense make sense in the context of this official sentence.

This sentence says that according to a prediction, a good number of executives belonging to a particular ethnicity will do something within the next ten years.

So in this part of the the sentence, the author talks about an event that will take place over the period of ten years. We do not have any particular point in time before which this action will be completed.

Hence, use of future perfect tense verb will have left is not correct here.

Since the sentence intends to present an event that will take place in future use of simple future tense verb will leave is correct.


Now let's talk about the meaning of the sentence.The sentence intends to say that per a prediction, a good number of executives belonging to a particular ethnicity will leave their corporate jobs within the next ten years to start their own business. This situation has been compared to a situation in the present. In the present, many engineers and computer experts belonging to the same ethnicity have already done so, i. e., they have already left their jobs to start their own business.


Hope this helps.
Thanks.

So statement is a combination of a prediction and 100% certainty about a particular event.
That is why we used "will" in combination of "predict".

Some of examples suggest the use of would in case of prediction and when you are not sure about the events that are going to occur in near future.

I predict that he will have finished his homework within five days.
I predict that he will finish his homework by tomorrow 10:00pm.

Could anyone explain it further?

This question is poorly written "corporate job" is incorrect.

It should be "a corporate job" or 'their corporate job' or otherwise.

Check the source please

In case of past perfect tense we consider a statement such as "by 1982 John had cleared his doctoral program" correct since we say that John had cleared the program had happened before 1982 end. So on similar lines the statement "over ten years" can convey that executive will have left the job before the completion of these 10 years?

The Census Bureau predicts that within the next ten years a significant number of Black executives in US will have left corporate job so as to start their own businesses, as many Black engineers and computer experts have done already.

(A) have left corporate job so as to start their own businesses, as many Black engineers and computer experts have done already.

(B) have left corporate job so they can start own businesses, as have many Black engineers and computer experts already.

(C) have left corporate job to start their own businesses, as did many Black engineers and computer experts already.

(D) leave corporate job to start their own businesses, as many Black engineers and computer experts have done already.

(E) leave corporate job so as to start their own businesses, as many Black engineers and computer experts already have left.

I am unable to find any error in option E. Can you please help me how to select between options D and E.

The clearest problem with (E) is the misuse of the idiomatic structure "so as to."

"So as to" is used to communicate that one thing is done to directly cause another to happen.

Example:

John painted the steps white so as to ensure that people would see them clearly.

That sentence conveys that BY PAINTING THE STEPS John ensured that people would see them clearly.

Let's see why "so as to" doesn't work in (E).

The Census Bureau predicts that within the next ten years a significant number of Black executives in US will leave corporate job so as to start their own businesses, ...

That wording suggests that BY LEAVING THEIR JOBS, executives will start their own businesses.

Since one would not start a business by leaving a job, that meaning is illogical.

Hello waytowharton,

We hope this finds you well.

To answer your query, on GMAT "so as to" is generally an incorrect usage; "so + cause + as to + effect" is the correct, idiomatic usage.

We hope this helps.
All the best!
