Which noun means a guess formed with little evidence?

• A. Conjecture
• B. Dearth
• C. Ephemeral
• D. Didactic

Answer: (A)

The main idea here is choosing a word that means a guess formed with limited evidence. A conjecture is exactly that: a guess or conclusion drawn from incomplete information, often with some reasoning but not proven. It captures the sense of forming a hypothesis that needs more evidence to be confirmed.

Think of it this way: if you observe a few clues and propose an explanation based on them, you’re making a conjecture. In everyday use, it’s a cautious, speculative idea rather than a surefact.

The other terms don’t fit this sense. Dearth means a shortage or scarcity, not a guess. Ephemeral describes something short-lived, not a belief or hypothesis. Didactic refers to teaching or moralizing in tone or aim, not to guessing or inference.

So the best fit for a noun meaning a guess formed with little evidence is conjecture.
