verb tense error

<p>hello guys, im having a problem with these sentences</p>

<p>Is this sentence correct?</p>

<p>After Margo returned to Dayville after ten years, the small town seems much livelier than it had been when she was growing up there..</p>

<p>the incorrect answer is the verb seems and i think it must be changed to seemed. why is that so? does the verb tenses in a sentence have to be in a same form
'</p>

<p>im confused with the word "after" and i dont know what to use, present or past. what should i do?</p>

<p>Thanks!</p>

<p>i think it should be seemed</p>

<p>So every verb tense on 1 clause should be the same? Is that the rule? Is there an exception?</p>

<p>Thanks!</p>
