Hi,
I believe it's B, "<span>The thermostat, which controls the temperature in the house, broke last night."
~Elisabeth</span>
The answer to #4 is "By" because a preposition word is a word that procedes to a noun or a pronoun. Some examples are "after", "against", "before", "behind", "below", ect... In this case the preposition is "by" and it procedes to the words "royal proclamanation"
It’s an incomplete sentence.
Is this Bud not Buddy? I haven't read it all and, how can we answer if we don't know the book? Please attach it!
The heading can be omitted! Hope this helped.
