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-
<u><em>1. The police are prepared in case there is a riot.</em></u>
Here, the noun "police" refers to the whole police as a group. So, it will take the plural verb form "are".
<u><em>2. The poor are helped by government programs.</em></u>
Here, the noun "poor" refers to the general population who are poor. So, the verb used will be "are".
<u><em>3. Sensitivity to other people's feelings makes Giorgio a kind person.</em></u>
Here, the subject is Giorgio, a singular noun. Thus, we will use the simple present form of the verb in the singular form "makes".
<u><em>4. The news about the long-range effects of air pollution on the development of children's lungs is disturbing.</em></u>
Here, the noun is "news" which is singular. So, the verb or helping verb "is" is used.
