I had selected A instead of D because though D has similar construction and I understand the point of present perfect not required here as the non-underlined section mentions "originally", thus negating the use of present perfect and past tense, emerged is a good choice.

However in the option D, emerged comes after originally and thereafter a comma. I got confused on whether this is a verbed modifier. I still need this clarification

D it is
A. has emerged from an animal host in less populated regions of Africa where there is more frequent contact [present perfect tense is not required] wrong
B. was emerging from an animal host in a sparsely populated region of Africa where there is contact more frequent [past continuous tense is wrong, the construction of B is also wrong where there is contact more frequent is wrong]
C. emerged from an animal host where there is more frequent contact in a sparsely populated region of Africa ["where"must modify a place, here it is modifying animal host, less populated regions is better] wrong
D. emerged from an animal host in less populated regions of Africa where there is more frequent contact [perfect and right]
E. was emerging in a sparsely populated region of Africa from an animal host where there is more frequent contact [again past continuous is wrong, from an animal host must be close to the noun it is modifying]

Actually right option is using the placement of emerged right after originally because it shows that initially how one thing emerged. In fact present perfect is wrong because something has happened in the past.

ruchi857, I don't see a comma in any of the choices. "Emerged" is the verb for the subject "Ebola virus." It's not a modifier.

A. has emerged from an animal host in less populated regions of Africa where there is more frequent contact

B. was emerging from an animal host in a sparsely populated region of Africa where there is contact more frequent

C. emerged from an animal host where there is more frequent contact in a sparsely populated region of Africa

D. emerged from an animal host in less populated regions of Africa where there is more frequent contact

E. was emerging in a sparsely populated region of Africa from an animal host where there is more frequent contact


look at choice A and C. why present perfect is wrong here.
2 cases for present perfect
first, it is used to show an action from the past until presetn. this is not the case in here.

second , it is used to show a finished action in an unfinished time frame. it sound good that it is the case in here. but no.

the finished action must be happen in the unfinished time frame. this action must go with an unfinished time words such as this month or this year. I have learn english this month. the implication is that in the period of this month (until present), I have learned english.

so, second case is not fit inhere. "emerging" dose not happen in an unfinished time. there is no unfinished time in this context of "believed" .

so, has emerged is incorrect inhere.

this analysis require proper understanding of present perfect.
