Which word means 'something that comes before, especially something that announces or suggests something is on its way'?

• A. Predecessor
• B. Omen
• C. Precursor
• D. Harbinger

Answer: (C)

The idea being tested is the word that means something that comes before and foreshadows what is to come. A precursor fits this idea best because it describes a person, thing, or event that precedes another and signals or helps pave the way for what follows. It’s the early stage or sign that indicates a later development, often used across fields like science, history, and medicine to show how one thing leads to another.

For example, early industrial experiments can be seen as precursors to modern manufacturing, or a small scientific finding can be a precursor to a major theory. This sense of being an antecedent that points toward what’s coming is what makes precursor the most precise choice here.

Predecessor focuses on someone who held a position before another person, not on signaling or leading to a future development. An omen is a sign of something that will happen, often with a supernatural or interpretive flavor, rather than a concrete preceding influence. A harbinger signals that something is coming, but the term emphasizes the sign itself rather than the thing that comes before to lead to the next stage; precursor covers both the temporal aheadness and the signaling aspect in a more general, foundational sense.
