Grammar reviewWhere, when, and why: reading the answer to find the question
This exercise works backward: you're given the answer, and you have to figure out which question word makes it fit. The trick is to look at what kind of information the answer actually gives.
Where asks about a place. If the answer names a location: Q: ___ did she leave her keys? A: On the kitchen counter. → Where
When asks about a time. If the answer names a moment, day, or duration: Q: ___ will the results be ready? A: By Friday. → When
Why asks for a reason. If the answer explains a cause or justification, often starting with because: Q: ___ is the shop closed? A: Because it's a public holiday. → Why
Watch out: some answers are short and could seem ambiguous at first ("By the end of the week" is a time, not a place), so always check what kind of information is actually being given before choosing.
