First off do you mean the game tetris? If so here is the answer:
Tetra is a prefix which means “four” and is used when forming compound words. In tetris, we use pieces (called tetrominos), which are formed by combining 4 small blocks (called minos). There are 7 possible types of tetrominos named after the letters that they resemble: I, O, L, J, T, S, and Z.
The compound noun in the sentence is A. life cycles.
<u>A compound noun is a word formed by two or more words</u>. The first one generally indicates the type of object/person; in other words, it classifies the object or person presented in the second word. Furthermore, compound nouns have a different meaning than the meaning of the two words taken separately.
In this sentence,<u> "life cycles" is a compound noun because it has been formed with the words "life" and "cycles", which are also two nouns.</u> "Life", in this case, is indicating the kind of cycle that the sentence is referring to. In that way,<u> the compound noun "life cycles", defined as the series of stages that a living organism goes through during its whole life, does not have the same meaning than the words "life" and "cycles" taken alone</u>.
Answer: (B) Mann is enthusiastic about his ability to help others with his Bicycle Lending Library.
Explanation:
I am unsure as to which book or text this refers to but the phrase ''<em>Head over Heels</em>'' is used to describe a person who is very much in love with or enthusiastic about something. For instance, ''Mark is head over heels for badminton'' means that Mark really love badminton.
In using the phrase ''head over wheels'', the author is making a play on the phrase to describe that Mann is enthusiastic about something bicycle related so the option that he is enthusiastic about his ability to help others with his Bicycle Lending Library must be right.
C. The author uses a simile to compare the feeling of nervousness to melting because the sentence uses the word "like," which is an underlying hint to similes. Without it, it would be a metaphor.
