What is the MINIMUM number of grammatical or logical violations present in the following sentence if it is proposed as the opening sentence of a paragraph?
"However, it failed to prove the hypothesis."
C
Step-by-Step Solution
Key idea: An opening sentence must be independent and cannot contain dependent pronouns or contrasting connectors.
Step 1: Check for contrasting connectors. The sentence starts with "However", which requires a preceding idea to contrast with. This is Violation 1.
Step 2: Check for dependent pronouns. The sentence contains "it" with no antecedent in this sentence. This is Violation 2.
Step 3: Total minimum violations = 2.
Answer: C
