<p>From about A.D 700 to 1600, sculptors created nearly 1000 colossal rock statues on the remote and tiny Eastern Island. No error</p>
<p>I thought "created" should be "had created" since the sentence mentions a timeframe, but the correct answer is E, no error.</p>
<p>Any ideas?</p>
<p>Of course there is no error !Why do you think there is ?
'had created' is a past perfect tense.You do not need past perfect in this sentence,the past simple 'created' is fine.</p>
<p>If you said "had created," you would expect the sentence to go on and say something else like:</p>
<p>From about A.D 700 to 1600, sculptors had created nearly 1000 colossal rock statues on the remote and tiny Eastern Island, until...</p>
<p>Just saying created is fine here. Created implies a habitual or repeated action, not only a one time thing. Therefore, you could say created even though it mentions a timeframe.</p>
<p>^ thanks for clarifying this up.</p>
