Question

1) Edgar Allan Poe wrote the short story "The Tell-Tale Heart." (2) Poe wrote the story in 1843. (3) In the story, a man is haunted by an old man's eye. (4) He thinks it looks like the eye of a vulture. (5) We soon learn that the haunted man has a mysterious disease. (6) The disease has made the man insane. (7) He does not know it. (8) For seven nights, he sneaks into the old man's room. (9) He watches the sleeping man. (10) I will not tell you what happens next because I do not want to spoil the story for you. Which is the most effective way to combine sentences (6) and (7)? Not known by him, the disease has made the man insane. Making the man insane, the disease is not known by him. The disease has made the man insane, but he does not know it. The disease has made the man insane he does not know it.

Answer 1

The best option is C) The disease has made the man insane, but he does not know it.

Step-by-step explanation:

The last option simply puts the two independent clauses together with no punctuation or conjunctions whatsoever. It can, thus, be eliminated. The other options are not appropriate because they change the meaning of the original sentences. The best option is definitely the third one. It uses punctuation - a comma - and a coordinating conjunction - but - to put together two independent sentences. The conjunction "but" indicates contrast, which lies in the fact that the man does not know the disease has made him mad.

Therefore:

(6) The disease has made the man insane. + (7) He does not know it. = The disease has made the man insane, but he does not know it.
