Question

what does the following sentence suggest?
the local campground, which features tents with comfortable mattresses, electricity, and portable heaters, is part of a camping trend called \glamping,\ or luxury camping.
there is more than one local campground.
there is only one local campground.

Explanation:

In English grammar, the non - restrictive relative clause "which features tents with comfortable mattresses, electricity, and portable heaters" is used. A non - restrictive relative clause is used when the information it provides is additional and not essential for identifying the noun. If there was only one local campground, a restrictive relative clause (without commas) would be more likely. The use of a non - restrictive clause implies that there are other local campgrounds (the one described is just one of them).

Answer:

There is more than one local campground.
