I believe the answer is E as well. But here is a question. Would this be right?

To use past perfect we need two actions happening in the sentence, one preceding the other. There is only one action here. Anyone disagrees?

There are no two past events, so no need for Past Perfect.

A “calendar stick” carved centuries ago by the Winnebago tribe may provide the first evidence that the North American Indians have developed advanced full-year calendars basing them on systematic astronomical observation.
(A) that the North American Indians have developed advanced full-year calendars basing them – “have developed” is present perfect implies that they are still developing the calendars which might not be true
(B) of the North American Indians who have developed advanced full-year calendars and based them – we are not concerned about the “evidence of North American Indians”
(C) of the development of advanced full-year calendars by North American Indians, basing them – “basing them…” modifies American Indians instead of calendar -wrong
(D) of the North American Indians and their development of advanced full-year calendars based - wrong – again “the evidence of North American Indians” is not the concern
(E) that the North American Indians developed advanced full-year calendars based – Best answer – simple past tense, “based on systematic…” correctly modifies calenders

E

Evidence of native americans making calenders based on observations, not evidence of native americans.

A – pronoun error – them is not clear
B – pronoun error and base should modify calendar (if there is a comma, base can modify Indians)
C – them not clear
D – there is not clear and separating Indian and development distort the meaning

E for me

(A) that the North American Indians have developed advanced full-year calendars basing them
(B) of the North American Indians who have developed advanced full-year calendars and based them
(C) of the development of advanced full-year calendars by North American Indians, basing them
(D) of the North American Indians and their development of advanced full-year calendars based
(E) that the North American Indians developed advanced full-year calendars based

Pronoun ambiguity in A,B,C & D.

Hence E.

A “calendar stick” carved centuries ago by the Winnebago tribe may provide the first evidence that the North American Indians have developed advanced full-year calendars basing them on systematic astronomical observation.
(A) that the North American Indians have developed advanced full-year calendars basing them
(B) of the North American Indians who have developed advanced full-year calendars and based them
(C) of the development of advanced full-year calendars by North American Indians, basing them
(D) of the North American Indians and their development of advanced full-year calendars based
(E) that the North American Indians developed advanced full-year calendars based

Hint: the sentence provides an indication of a time the event occurred in the past. 9 times out 10, it means that simple past tense of the verb has to be used.
Eliminate A

B changes the meaning completele. Out!!!

"Evidence of" and "evidence that" are both correct depending on the sentence.

Evidence of + noun is correct such as "evidence of a murder case", but evidence that + clause is also correct like in this sentence.

D is incorrect. "Basing" is a present participle and it usually modifies the verb, but there is no verb here to modify in the first place.

E stands.

1. A “calendar stick” carved centuries ago by the Winnebago tribe may provide the first evidence that the North American Indians have developed advanced full-year calendars basing them on systematic astronomical observation.
A. that the North American Indians have developed advanced full-year calendars basing them

C. of the development of advanced full-year calendars made by North American Indians, basing them
D. of the North American Indians and their development of advanced full-year calendars based
E. that the North American Indians developed advanced full-year calendars based

IMO E.

I want to know idioms of evidence...
The N.A. Indians are not the evidence. And the use of their may make ambiguities.... And the use of present perfect too!
