1) We searched the car trunk, the pantry shelves, and the top of the refrigerator, but we could not find the box of cornflakes that we remember buying.

2)Belinda saw very little of the horror movie, for she shut her eyes when the violins began to play, when she heard the monster's footsteps in the dead leaves, and when characters started screaming.

3) Teresa was expecting a visit from her mother, so she spent the day cleaning the shelves of the refrigerator, scrubbing mold from the bathroom tile grout, and removing dog hair from the sofa cushions.

4)In regions of the world where poverty prevails, starvation and poor hygiene lead to disease.

Explanation:

In English, structures in  sentences MUST be balanced. That is to say, the sentence has to have parallelism in structures. In grammar, parallel structures are those which have the same grammatical structure. For example, in the first sentence several nouns are repited, and it would be incorrect if we put another structure (a verb phrase, for example) in the middle of a enumeration of nouns.

As in many languages, in English, the subject has to agree or concord with the verb; this is called subject/verb agreement. That is, if the subject is singular, the verb MUST be singular, and if the subject is composed of two or more people/objects, the verb MUST be plural. If not, there is a serious grammar mistake, which makes ungrammatical the complete sentence.
