Answer:
The correct answers are: -ing, -er and –ion.
Step-by-step explanation:
IMPORTANT: A verb is an action, whereas a noun is a person or thing.
- I read a lot every day in order to increase my vocabulary. (I read, you read, we read, etc… verb conjugation with pronouns)
- This reading was rather dramatic, I didn’t like it. (Reading as a noun referring to a piece of writing or thing that can be read).
- I play soccer with my friends every Saturday. (Again, the conjugation of the verb play with different pronouns.)
- Lionel Messi is a very famous Soccer Player. (Player as a noun here, is the person who performs the action, in this case of playing soccer.)
- We communicate every day in order to maintain a control in the office. (The action of “communicate” can be conjugated with every pronoun.)
- The communication in the office among the coworkers is horrible. (With the suffix –ion becomes a noun, a thing.)
And the suffix -ed cannot be possible as it can only change the verb to an adjective (a descriptive word).
