Well, despite the fact that you haven't provided me with sentence 8 for review, I can -- fortunately for you -- say that option B MUST be the correct answer ... based solely on pure logic and a strong command of English.
Answer:
The answer is B. fails to mention any facts about Thomas Young.
Explanation:
The student has not provided more facts. When writing facts, it should have at least 14-20 lines or it cannot come in the classification of a fact. Also, a fact should also provide accurate information about that person or it is not a fact.
Hope this helps....
Have a nice day!!!!
