The report indicates that customer satisfaction ___ steadily since March.
答えを見る
正解: C) has improved
'Since March' marks a starting point ('ever since March'), expressing an ongoing change from the past to now, so the present perfect 'has improved' is correct. 'Improves' is present tense and doesn't convey continuity. 'Improved' is past tense and would need the present perfect to combine properly with 'since'. 'Improving' is a participle and can't stand alone as the main verb.
