Question

Determine whether the given topic is more obviously suitable for a report or an essay.

Answer 1

A report is a presentation and analysis of findings and data from practical research, aimed at investigating, exploring and sharing specific information. Meanwhile, an essay seeks to answer a question based on research too, but through the writer's own point of view, to support his own conclusions.

Taking this into account, we may say that annoying people on cell phones is a topic more suitable for an essay.
