  3. Interpretation
  4. negate
  5. Dispute
  6. Refute

I will give a brief explanation of each word, which will then help us reach the final answer.

With my definitions in mind, the matching words and definitions are:

  2. Validity - <em>e. Think about the pros and cons carefully.</em>
  3. Interpretation - <em>f. Being logical, accurate, and factual.</em>

Which sentence uses correct subject-verb agreement?
Karolina [17]
The correct answer is The alligator slipped quietly into the water.
