Soru: Choose the correct option to fill in the blank: "She ________ to the cinema last night because she was studying."
Options: a) didn't go b) doesn't go c) isn't going
Çözüm: Look at the time clue "last night"—this indicates past tense. The sentence structure shows a negative past action. Option a) "didn't go" uses the past simple negative form (did not + base verb), which matches "last night". Option b) is present simple, and option c) is present continuous, both incorrect for past time. Thus, the answer is a) didn't go.
