The acetyl group some of the electron density the nitrogen, making it much basic; the nitrogen of this amide is under the reaction conditions. The N retains enough electron density to share with the benzene ring, so the NHCOCH3 group is still an activating -director, though weaker than NH2.

The gaps are filled using the following;

1. removes

2. from

3. less

4. Protonated

5. Ortho, para

Explanation:

Electron density is removed from nitrogen in acetyl group which is why it is less basic

The complete sentences is now written as;

The acetyl group removes some of the electron density from the nitrogen, making it much less basic; the nitrogen of this amide is protonated under the reaction conditions. The N retains enough electron density to share with the benzene ring, so the NHCOCH3 group is still an activating ortho, para director, though weaker than NH2.
