I found subject and predicate agreement difficult. Please read the following sentences:
1. The old couple __________( love, loves) childre's literature, and Alice in Wonderland and Harry Potter are two favorites of theirs.
The key is 'love'. Is 'couple' a collective noun? If it is can I use 'loves' to refer them as a whole instead as individual?
2. 'force' should always be used as a singular noun. Is that right? If it is, then 'The labor force consists of 40 people' instead of 'The labor force consist of 40 people'. Is that right?
3. What equipment we need at the moment are trucks, bulldozers and drills.
Here 'are' is decided by the words following it. If only 'truck' follows the verb then it should be 'is'. Is that right?
Looking forward to hearing from you.
Thank you in advance.
