Explanation:

In the given sentences, the main thing to remember that will help us spot the error or chose the correct answer is to see the subject-verb agreement. This means that the number of the subject/noun is in sync or in agreement with the verb used with it.

The correct answers are as follows-

1. The police are prepared in case there is a riot.

Here, the noun "police" refers to the whole police as a group. So, it will take the plural verb form "are".

2. The poor are helped by government programs.

Here, the noun "poor" refers to the general population who are poor. So, the verb used will be "are".

3. Sensitivity to other people's feelings makes Giorgio a kind person.

Here, the subject is Giorgio, a singular noun. Thus, we will use the simple present form of the verb in the singular form "makes".

4. The news about the long-range effects of air pollution on the development of children's lungs is disturbing.

Here, the noun is "news" which is singular. So, the verb or helping verb "is" is used.
