"speculated for decades": "for" here prefers perfect tense. Hence eliminate A, B, C/

"had moved" agrees with "by the time". The adverb here is "at the time", so "had moved" is incorrect. "moved" is prefered.

Also, "appear at the peak of" makes the sentence awkward. "appeares to have been" correctly refers to the past. E is the correct answer.

Hey Broall,

I eliminated answer choices with "had moved" because there is no "past of the past" and past event to refer to.
Both the following events:
1. Anasazi moved from CC to somewhere else
2. Their culture was at the peak of evolution

happened at the same time. Hence, we do not need past participle.

However, IMO "have been" must be used only when the effects of the event still persists today. Anasazi culture was at its peak in the past. Hence, simple past would have sufficed here.

Hi I have doubt regarding the expression appears to have been
.
The sentence is in the past tense but we are using appears to have been .

I am no expert, but let me add my two cents.

We definitely need have speculated (present perfect) since the archaeologists had speculated in past
and are still speculating. It is not a point of time event (speculated, ie simple past tense) that happened in past.

Also appears (simple present - suggesting a fact) to have been (present perfect) makes sense since the effect is still continuing
as suggested by - have been .

Let me know if these helps!

adkikani, you're on the right track. The sentence is saying that it currently appears to us that the Anasazi culture was at its peak at the time of the move. So it appears (now) to have been (then) at its peak.

Please post the questions as per the rules of the forum.

As far as the answer is concerned, the biggest giveaway is the verb speculate

1) speculated Vs speculate Vs have speculated..
Speculation is an ongoing thing here, from a decade or so.. therefore you require present perfect HAVE speculated.
Only D and E left
2) D is awkward in the phrase " their culture appeared at the peak". The meaning gives a sense of physical appearance.. therefore appears to have been at peak is correct

Only E is left
