Sentence 9:
They emphasized the importance of good maternal and child health care, including the administering of vaccines?

1- replace They with it
2- change emphasized to emphasize
3- change the spelling of importance to importants
4- insert a comma after importance
5- remove the comma after care

I'm not sure in this one

It could be 1, but we can't tell because we don't know the antecedent.

I prefer to think 5 is wrong.

In Sentence 9, you are given a sentence that states "They emphasized the importance of good maternal and child health care, including the administering of vaccines." Based on the options you provided, here's how each one would affect the sentence:

1- Replace "They" with "It":
If you replace "They" with "It", the sentence would read: "It emphasized the importance of good maternal and child health care, including the administering of vaccines." This option is grammatically correct and the sentence still makes sense.

2- Change "emphasized" to "emphasize":
If you change "emphasized" to "emphasize," the sentence would read: "They emphasize the importance of good maternal and child health care, including the administering of vaccines." This option changes the verb tense from past tense to present tense. Depending on the context, either past or present tense could be appropriate.

3- Change the spelling of "importance" to "importants":
If you change the spelling of "importance" to "importants," the sentence would read: "They emphasized the importants of good maternal and child health care, including the administering of vaccines." This option is grammatically incorrect as "importants" should be "importance".

4- Insert a comma after "importance":
If you insert a comma after "importance," the sentence would read: "They emphasized the importance, of good maternal and child health care, including the administering of vaccines." This option adds unnecessary commas to the sentence and disrupts the flow.

5- Remove the comma after "care":
If you remove the comma after "care," the sentence would read: "They emphasized the importance of good maternal and child health care including the administering of vaccines." This option removes the comma before the word "including." With this change, the sentence retains its meaning and becomes more concise.

So, the incorrect options are 3 (change the spelling of "importance" to "importants") and 4 (insert a comma after "importance"). The correct options are 1 (replace "They" with "It"), 2 (change "emphasized" to "emphasize"), and 5 (remove the comma after "care").
