<span>The correct answer is the first choice: ", her house bedecked in garlands of flowers," The sentence, therefore, should read, "Señora Alvarez, her house bedecked in garlands of flowers, waited excitedly for her guests to arrive." The inserted phrase is not necessary for the sentence to be grammatically correct, so therefore it is surrounded in commas, as an aside.</span>
<span>There are two mistakes in this sentence.
The first mistake is the use of the word "less" when used with the noun "cars." Instead, the correct word should be "fewer." In general, use the word "fewer" when the number of objects can be counted; use the word "less" when the objects cannot be counted. For example: fewer cars on the road (cars can be counted), but less traffic (traffic is a general noun and cannot be counted).
Also, note that the verb "means" does not agree with the subject "cars." Therefore, the correct sentence should read: Fewer cars on the road mean less traffic.</span>
Something that McCarthy wanted to do is to prove that Gustave Duran was a communist.
McCarthy actually proved this by narrating when Gustave Duran served in the communist international brigade.
Also, McCarthy claims that John Service friendship with China and communism was the only hope for the United States.
Hope this helps.
