Which option best defines "thinly dispersed or scattered"?

The term "sparse" aptly defines "thinly dispersed or scattered." In various contexts like population distribution, vegetation, or any item that is not densely packed, "sparse" conveys the idea of something being thinly spread out or available in limited quantities. This term can effectively describe situations where elements are not clustered together but rather exist independently across a larger area.

In contrast, the other choices do not encapsulate the same meaning. "Sway" refers to movement or control over something, which does not relate to distribution. "Entreat" means to ask someone earnestly or anxiously to do something, and thus does not reflect dispersion at all. "Harrow" pertains to agricultural tools or can mean to cause distress, but it does not invoke the concept of something being scattered. Therefore, "sparse" is the most accurate choice for describing something that is thinly dispersed or scattered.
