The s<span>entences below include only prepositional phrases (no participial or absolute phrases and no dependent clauses) are the below:
</span><span>A.)Then one, and then another of the boys carne up on the far side of the barrier of rock, and he understood that they had swum through some gap or hole in it.
B.)There was no one visible; under him, in the water, the dim shapes of the swimmers had disappeared.</span>
A. Gerunds generally end in -ing, and the subject of the prepositional phrase "for meeting" is meeting, which means it is the object of a preposition. Hope this helps!
