1. The correct answer is: periodical index.
Magazines, DVDs, and books may be found anywhere. But libraries provide an index of periodicals that have been arranged by years and dates. This serves as a reference tool for people.
2. The correct answer is: dictionary.
The two mistakes in the sentence are "trophys" and "metals".
The plural form of "trophy" is "trophies" not "trophys" because the plural form of nouns that end in "-y" is usually "-ies".
In the sentence, "metals" is not wrongly spelled but it does not make much sense. It is quite strange to say to someone not to touch trophies and metals, the two objects do not seem to have any type of relationship. If you consider that the person is talking about awards and prizes, instead of metals, he or she is referring to "medals".
Even though there are two more mistakes, I don't think the question aims at those. Just remember that the sentence should start with a capital letter and finish with a full stop.
So the sentence would read: Do not touch trophies or medals.
I am going to go with C (simple sentence) on this one because after the and you do not have another complete sentence therefore it would not be considered a complex sentence. Hopefully this helps.
