Read each sentence to find out whether there is any grammatical error in it. The error, if any will be in one part of the sentence. The letter of that part is the answer. If there is no error, the answer is 'D'. (Ignore the errors of punctuation, if any).

Question

What should be the minimum Hamming distance \( d_{\text{min}} \) to guarantee correction of up to p errors in a given block code?

Answer 1

"Discuss" is one of a small set of verbs (like "reach," "resemble," "marry") that must be followed directly by their object, with no preposition in between.
So "discussed about the problem" wrongly inserts "about," where the correct form is simply "discussed the problem."
The other two parts of the sentence, the timing phrase and the closing clause, both follow standard grammar with nothing to correct.
Therefore, the correct answer is (A) We discussed about the problem so thoroughly.

Answer 2

A quick test for this type of error is to try removing the suspected extra word and see if the sentence still makes complete sense.

We discussed about the problem so thoroughly: Removing "about" gives "We discussed the problem so thoroughly," which reads perfectly and keeps the same meaning. Since removing the word changes nothing but improves the grammar, "about" was never needed, confirming this part is wrong as written.
on the eve of the examination: There is no extra or missing word here; every word plays a necessary role in the phrase, so this part passes the test.
that I found it very easy to work it out: Every word here is also necessary to the clause's meaning, so no error is found in this part either.
No error: This option would apply only if the substitution test found nothing wrong anywhere, but it did flag part (A).

The substitution test isolates "about" in part (A) as the unnecessary, incorrect word.

Therefore, the correct answer is (A) We discussed about the problem so thoroughly.
