The answer is
- <span>The soldiers crept cautiously through the tunnel.</span><span>.
- </span><span>I was informed that the bus would arrive in 45 minutes.
Prepositional phrases begin with a preposition and will be followed by noun, pronoun, gerund, or clause which displayed by two sentences above
(Through) + ( the tunnel)
(in) + ( 45 minutes) </span>
The period should be placed behind the d in mud
<span>The answer is that an introductory adverb clause is usually followed by a comma. This is to introduce a pause to separate the two clauses. For example, When you go to the beach, you like to play with the sand and build sand castles. There you see that the indroductory clause, "when you go to the beach" is separated from the main clause "you likde to play with the sand and build sand castles" by a comma.</span>
