Answer:
Manny y Clara leyeron revistas.
Step-by-step explanation:
To solve this exercise, first, you have to look at the meaning of the sentence. You should focus on the word "magazines" and think which verb collocates with this noun; in other words, which action can be performed with magazines, and you will find out that the verb that suits this sentence is "leer" (read). Then, you have to pay attention to the subject of the sentence "Manny and Clara". This is a plural subject (ellos), so you need the verb leer in Spanish conjugated in the 3rd person plural to agree with that subject: Manny y Clara leyeron.
The other options are not possible because of meaning: Cayeron / cayo means "to fall". Oyo /oyeron means "to hear". Destruyo/ destruyeron means "to destroy". Contruyo/construyeron means "to build". None of these meanings is appropriate for the context of the sentence. Generally, books are read, and not fallen, heard, destroyed or built.
There is one last option "leyo", which is not possible because of grammar. Leyo is conjugated in the 3rd person singular, and as the subject is "Manny and Clara", you need a verb conjugated in the 3rd person plural for the sake of agreement. Therefore, this option is discarded, too.
