The answers are -The soldiers crept cautiously (through the tunnel.) -I was informed that the bus would arrive (in 45 minutes.)
Explanation:
The sections "through the tunnel" and "in 45 minutes" begin with a preposition, which are words such as in, on, under, through, out, etc., and the preposition is followed by a noun, which is known as the object of the preposition. These two elements are the basic elements that compose a prepositional phrases. Moreover, these two sections modify the verb of the sentence, which is a function of prepositional phrases, in the case of the first sentence the prepositional phrase describes the action of "crept", while the second section describes in time the action of "arrive".
