Fill in the blank with an appropriate option.

The social ________ is going to meet with all of us tomorrow with the plans so we can make a decision.

worker

The correct option to fill in the blank is worker.

The word "worker" refers to a person who does manual or physical work. It is the most appropriate word to use in this context, as the social worker is going to meet with all of us to discuss the plans for the community.

The other options are not as appropriate:

• Army refers to a large organized group of people who are trained to fight. It would not be accurate to use "army" in this context, as the social worker is not a member of the army.
• Toddler refers to a young child who is just learning to walk and talk. It would not be accurate to use "toddler" in this context, as the social worker is not a toddler.
• Labour refers to physical work or toil. It would not be accurate to use "labour" in this context, as the social worker is not doing physical work.
