Which word means 'doubtful or suspicious'?

• A. Questionable
• B. Undecided
• C. Not totally good or honest
• D. Doubtful

Answer: (D)

This item tests your ability to pick a word that conveys both uncertainty and suspicion. Doubtful directly describes a lack of certainty about the truth or likelihood of something, and in everyday use it can also carry a sense of skepticism or mistrust, which aligns with the idea of being suspicious. That direct link to both uncertainty and potential distrust makes it the best fit for the prompt. For example, you might say, “The evidence seems doubtful,” to express both uncertainty and a hint of suspicion about its reliability. The other options either shift toward unrelated ideas (like choosing or trustworthiness without doubt) or are less exact in capturing the combined sense of doubt and suspicion.
