Q1. Choose the most appropriate option to fill in the blanks: “Is dad in?” “No, he isn’t. He ____________ home an hour ago. He _____________ yet.”
A Leave, not returned
B Left, has not returned Correct
C Leaves, didn’t return
D Will have, has not returned
Explanation
The phrase “an hour ago” requires the simple past, so “left” fits the first blank: he left home an hour ago. The word “yet” in a negative sentence points to the present perfect, so “has not returned” fits the second blank. “Leave, not returned” lacks the needed finite past verb and auxiliary. “Leaves, didn’t return” wrongly uses the simple present with “ago” and the simple past with “yet”. “Will have, has not returned” is grammatically unsuitable because “will have home” does not express leaving.
