Explanation

They had finished their homework by the time we arrived.

ہمارے پہنچنے تک وہ اپنا ہوم ورک ختم کر چکے تھے۔

The correct answer is "Had" because:

• The sentence uses the past perfect tense.
• The past perfect is used to show that one event happened before another event in the past.
• In this case, the homework was completed before "we arrived."

Explanation

The pattern is: "The more it is rubbed, the more scent it yields" (or "does it yield" in inverted form for emphasis).

The first part must follow "The more + subject + verb" structure.

Explanation

“Each of the boys” is grammatically correct and takes a singular verb (“is wearing”).

“On the team” is the standard preposition (not in for team in this context).

Explanation

“By the end of the week” indicates a past time before another past time → use past perfect tense (“had given”).

Phrasal verb “give up” must not be split incorrectly in this context.

Explanation

When referring to a person (a student), we use "who" (not that or which).

"The one who" is the proper structure for defining a person with certain qualities.
