Helen Keller, prolific author and speaker, could neither see nor hear.

Answer 1

Let's evaluate the sentences for correct comma usage:

1. **Although she could neither see nor hear Helen Keller, wrote prolifically.**
- This sentence is incorrect because the introductory clause "Although she could neither see nor hear Helen Keller" lacks a proper subject for the main clause. A correct version might be something like: "Although she could neither see nor hear, Helen Keller wrote prolifically."

2. **The woman, who spoke so eloquently, was Helen Keller.**
- This sentence is correct. The commas are correctly used to set off the non-essential clause "who spoke so eloquently," which adds additional information about "the woman."

3. **Helen Keller, did not let obstacles deter her from reaching her goals.**
- This sentence is incorrect because there should not be a comma after "Helen Keller." It should read: "Helen Keller did not let obstacles deter her from reaching her goals."

4. **Helen Keller, prolific author and speaker, could neither see nor hear.**
- This sentence is correct. The commas are used correctly to set off the non-essential appositive phrase "prolific author and speaker," which describes "Helen Keller."

In summary, the sentences with correct comma usage are:
- **The woman, who spoke so eloquently, was Helen Keller.**
- **Helen Keller, prolific author and speaker, could neither see nor hear.**
