hi ajit257,

Well you can start the sentence with "that clause" , I sad that it is not preffered.

so, why D is wrong here.

first look at "so poorly educated and trained" so needs a compliment "that" -for sexample "so many young recruits to the United States work force are so poorly educated and trained that"
- "so (adjective) that" - is correct usage
- "so .(adjective) why: -is wrong usage , please refer MGMAT SC chapter 9 "idioms" for more details.

second.
the intended meaning is the following
some people are worried about smth and the dependent clause explains why they are worried.
Ask yourself about what word is the most useful to explain this WHY relationship?

informally, very often people use the construction "that's why" to explain cause-effect relationship.
Formally the word BECAUSE is used fot that.

In our sentence anw D uses wrong, or informal construction "That .....why" with a lot of words between them.
It is much better to use BECAUSE.

Read the sentence vice versa.
"many business executives fear this country will lose its economic preeminence (WHY?) BECAUSE many young recruits to the United States work force are [strike]so[/strike]poorly educated " and this is perfectly clear sentence.


Moreover, D starts with "That..." clause which is not the subject of the sentence.

Hi Pkit,
Thanks for your reasoning. I have a small doubt though, I was told you can begin a sentence with 'that' if it introduces the clause that is the subject of the sc.
eg...

The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably on a spectrum of genetic relatedness.

A. The fact of some fraternal twins resembling each other greatly and others looking quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably
B. That some fraternal twins resemble each other greatly while others look quite dissimilar highlights an interesting and often overlooked feature of fraternal-twin pairs, namely that they vary considerably
C. With some fraternal twins resembling each other greatly and others looking quite dissimilar, it highlights an interesting and often overlooked feature of fraternal-twin pairs, namely considerable variation
D. With some fraternal twins resembling each other greatly and others looking quite dissimilar, it is a fact that highlights an interesting and often overlooked feature of fraternal-twin pairs, namely a considerable variation
E. Because some fraternal twins resemble each other greatly and others look quite dissimilar, this fact highlights an interesting and often overlooked feature of fraternal-twin pairs, namely they vary considerably

Here the correct ans is b.
So what is the difference. Please advise

Even i like the explanation....

Answer is A. This is an OG question.

In D there are two errors. 1. ‘That something is why’ is not an acceptable idiom. ‘That something is the reason why’ is the accepted version. 2. A comparative idiom that is started with ‘so’ has to be completed with a companion such as ‘that’ or ‘as’
