Which sentence uses the word "than" or "then" in a way that is often contested or identified as "wrong"? a) if you are so good at fixing broken appliances, then why don't you fix the leaky refrigerator? b) rather than argue over the definitions of certain words, let's just agree to table this discussion. c) at first, i was unsure about going to the gym, than i went for a few days and found out i loved it! d) when margaret told me that she was the only one going to the dance, i said, "i"m not sure i'm going then."

what is the passage

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
