Identify the underlined error in the following excerpt:
More than 20 ceiling fan manufacturers, the American Lighting Association (ALA), and leading energy conservation groups invites everyone to join the fight to reduce energy consumption by turning off their central cooling systems and relying on ceiling, floor, desk, and wall fans to save trillions of kilowatt hours of energy consumption.
- American Lighting Association (ALA)
- desk, and wall fans
- no errors
The answer says:
"Invites" does not match the plural subject of the sentence.
This is very vague explanation. Can someone please elaborate.
