At one time, he, him, and his were used to represent individuals of either gender, but this practice is no longer acceptable. change the pronouns in these sentences so that both ales and females are represented.

a) No one has to stay in his seat after the bell.
b) A library user should take care of his books.
c) Every doctor should listen to his patients.
d) Each person should prepare himself for the test.

I'll get you started --

a) Students do not have to stay in their seats after the bell.

I'll be glad to check your changes for the other sentences.

b) A library users should take care of their books.

c) Doctors should listen to their patients.
d) Every person should prepare themselves for the test.

b) and c) are correct.

d) Everybody should prepare themselves for the test.

Thank you so much!!! (:

You're very welcome.

d) is still incorrect whether you use "Every person" or "Everybody" (singulars) and then use "their" (plural). Try this:

All students should prepare themselves for the test.

Also, a) should be this: "All library users should take care of their books."

To change the pronouns in these sentences so that both males and females are represented, we can use gender-neutral pronouns. Here are the revised sentences:

a) No one has to stay in their seat after the bell.
b) A library user should take care of their books.
c) Every doctor should listen to their patients.
d) Each person should prepare themselves for the test.

In these revised sentences, the use of "their," "themselves," and other gender-neutral pronouns allows for a representation of individuals of all genders.
