In the question below, a part is omitted which is then replaced by a blank. Choose the word from the given options that will fit into the blank most appropriately.

The professor ended the lecture after a long class __________.

Correct option is D

Sentence given:
The professor ended the lecture after a long class __________.
Step 1: Context clue
· The sentence describes what happened during the long class before the professor ended it.
· So, the missing word must describe an activity of the class.
Step 2: Check options
(a) raise
· Meaning: lift up, increase (बढ़ाना, उठाना).
· Doesn’t fit grammatically after “long class.”
· Incorrect.
(b) record
· Meaning: to register, to capture data (रिकॉर्ड करना).
· “long class record” is awkward and meaningless.
· Incorrect.
(c) discuss
· Root form; grammatically wrong because it should be noun form discussion.
· Incorrect.
(d) debate
· Meaning: formal discussion, argument (वाद-विवाद).
· Example: The students had a debate on climate change.
· Fits perfectly: “after a long class debate.”
· Correct.
(e) break
· Meaning: pause, rest (विराम).
· But “after a long class break” is illogical — class cannot be both “long” and a “break.”
· Incorrect.
Step 3: Correct sentence
The professor ended the lecture after a long class debate.
Correct Answer: (d) debate
