Question

1. which topic is narrow enough to be the subject of a descriptive essay?

personal computers
the writer’s first laptop computer
computers
vintage computers

Explanation:

This topic is the narrowest: it focuses on a single, specific device (the writer's own first laptop), which provides a focused, specific subject for detailed descriptive writing. The other options are broader categories: "computers" is too general, "personal computers" covers a large group, and "vintage computers" still refers to a broad set of devices rather than one specific item.

Answer:

the writer's first laptop computer
