Question

1. which sentence contains a subject - verb agreement error? there are many reasons to visit ireland. neither my sisters nor my father have been to ireland. the team of scientists works hard to find solutions. the pants on the washer need to be washed.

Explanation:

In English grammar, when using "neither...nor", the verb agrees with the noun closest to it. Here, "father" is singular, so the verb should be "has" instead of "have". The other sentences have correct subject - verb agreement. "There are" agrees with "many reasons", "team" (singular) agrees with "works", and "pants" (plural - although a pair of pants can be seen as singular in some cases, here "pants" is plural in context) agrees with "need".

Answer:

Neither my sisters nor my father have been to Ireland.
