Question

Which sentence does not have an error in subject and verb agreement?

A.
The sun, warm and sunny, were shining on the lake.


B.
A slim chance at success was my only hope for the future.


C.
Muddy shoes and a rain-soaked jacket was in a heap on the floor.


D.
Don't a combination of oil and vinegar make a good dressing on the salad?

Answer 1

B. The other sentences either have singular subjects with plural verbs (the sun... were shining;       don't a combination... make) or plural subjects with singular verbs (shoes... was). 

Answer 2

I would also have to say B is the correct answer. Your verb is was and it agrees with chance, which in this case is your noun because at success would be a prepositional phrase. Small is an adjective that describes chance.

Hopefully this helps and good luck!! :)
