Scientists now believe that a part of the brain called the hippocampus might play a role in remembering the passage of time, long knowing that it is critically important for remembering past experiences.
A) Scientists now believe that a part of the brain called the hippocampus might play a role in remembering the passage of time, long knowing that it is critically important for remembering past experiences.

C) Having long known that a part of the brain is critically important for remembering past experiences, the hippocampus, scientists now believe might also play a role in remembering the passage of time.
D) While scientists have long known that a part of the brain called the hippocampus is critically important for remembering past experiences, they now believe that it might also play a role in remembering the passage of time.

OFFICIAL EXPLANATION
THE PROMPT
THE OPTIONS
→ Who has been long knowing? The scientists. Under the Modifier Touch rule, a noun modifier should be as close as possible to the noun it modifies.
What is the noun modifier doing at the end of the sentence?
→ It is true: comma + present participle (verbING) can modify the entire clause or the subject of that clause.
But something is strange about the placement of long knowing that.
No, the phrase does not trigger an ambiguous antecedent: neither the brain nor hippocampus makes sense as whatever "long knowing" refers to,
but that COMMA + ING form seems tacked on.
KEEP, But look for a better answer
Just one problem: no such verb exists.
The first part of the sentence lacks a working verb.
ELIMINATE B
→ Right after we read about "Having too long known that a part of the brain. . . ." we should be reading immediately about people who can or did know these things. Instead we read about the hippocampus.
Not good: thee use of having absurdly suggests that the hippocampus (and not the scientists) has long known something.
ELIMINATE C
→ The sentence uses a while to set up a dependent clause that depends on the independent clause after the comma.
→ The sentence uses a while to set up a dependent clause that depends for its meaning on the independent clause after the comma.
→ The word while creates sensible connection between the two clauses.
One the one hand, scientists knew that the hippocampus was important for memory, but on the other hand, they now believe that the hippocampus is even more important than before for a specific reason.
KEEP
ELIMININATE E
The best answer is D.
COMMENTS,
These answers are excellent.

Project SC Butler: Sentence Correction (SC2)
THE PROMPT
Quote:
• The sentence describes two things: one that scientists have long known and one that they now know.
THE OPTIONS
Quote:
• misplaced modifier
→ Who has been long knowing? The scientists. Under the Modifier Touch rule, a noun modifier should be as close as possible to the noun it modifies.
What is the noun modifier doing at the end of the sentence?
→ It is true: comma + present participle (verbING) can modify the entire clause or the subject of that clause.

No, the phrase does not trigger an ambiguous antecedent: neither the brain nor hippocampus makes sense as whatever "long knowing" refers to,
but that COMMA + ING form seems tacked on.
KEEP, But look for a better answer
Quote:
• The phrase AND they now believe indicates that another previous, parallel verb matches believe.
Just one problem: no such verb exists.
The first part of the sentence lacks a working verb.
ELIMINATE B
Quote:
• misplaced modifier
→ Right after we read about "Having too long known that a part of the brain. . . ." we should be reading immediately about people who can or did know these things. Instead we read about the hippocampus.
Not good: thee use of having absurdly suggests that the hippocampus (and not the scientists) has long known something.
ELIMINATE C
Quote:
• I do not see any errors
→ The sentence uses a while to set up a dependent clause that depends on the independent clause after the comma.
→ The sentence uses a while to set up a dependent clause that depends for its meaning on the independent clause after the comma.
→ The word while creates sensible connection between the two clauses.
One the one hand, scientists knew that the hippocampus was important for memory, but on the other hand, they now believe that the hippocampus is even more important than before for a specific reason.
KEEP
Quote:
• same modifier problem as problem A: now believing revers to scientists but is too far from its noun.
ELIMININATE E
The best answer is D.

A) Scientists now believe that a part of the brain called the hippocampus might play a role in remembering the passage of time, long knowing that it is critically important for remembering past experiences.
- Structural error (long knowing that it is critically important for remembering past experiences) - not properly connected to first part of sentence
- Meaning Error(a part of the brain long knowing.....)
B) Scientists having long known that a part of the brain called the hippocampus is critically important for remembering past experiences, and they now believe that it might also play a role in remembering the passage of time.
- Missing verb for Subject (scientist), "having" is acting as modifier
C) Having long known that a part of the brain is critically important for remembering past experiences, the hippocampus, scientists now believe might also play a role in remembering the passage of time.
- illogical meaning - the hippocampus Having long known............
- "the hippocampus" - dangling in between - Sentence has structural error
D) While scientists have long known that a part of the brain called the hippocampus is critically important for remembering past experiences, they now believe that it might also play a role in remembering the passage of time.
- Logically and grammatically seems fine
- CORRECT
E) Scientists have long known that a part of the brain called the hippocampus is critically important for remembering past experiences, now believing that it might also play a role in remembering the passage of time
- illogical modification by " a part of the brain now believing ......."
