Hi,

Why "Factor" is not chosen over "thing", It too fits in the sentence.

HELP!!

Hi,

In this test the language is very informal -conversational. Although 'factor' fits, as you say, it's not appropriate in this context. 'Factor' would be used in a formal/serious discussion as in: The important factor to remember when buying a car is whether to choose a diesel or petrol engine.
