Question

1-which option is correct?
Neither the climbers nor their guide ....
a) were ever seen
b) have ever been seen


2-Is this sentence correct?
Either my parents is to leave home.

Answer 1

1. B ....but change "have to has" because the subject closest the verb is singular, so the verb should also be singular.

2. That's a poorly structured sentence. It should be "Either of my parents is to leave home. " and that still does not make sense. ( Either is singular... it is also the sentence subject, so it must take a singular verb... "is".) This sentence should be reworded

Answer 2

For the first question, both A and B could be correct. It depends on whether you are speaking about them as if to say, they were never seen in that area while they were there, or they have never been seen since a certain time or event that has been mentioned earlier.

For the second question, the answer is no, this it not a correct sentence. In fact it is really not a sentence at all.

Probably the best thing to say here would be, "Either one or the other of my parents is to leave home."

But I'm really not sure of what you mean, exactly. Will one of the parents definitely leave? Are both of them going to stay at home and NEITHER will leave?

Could you say, simply, "One of my parents will have to leave home"?

I hope this helps a little bit.

Answer 3

For 1, both verb tenses are correct - the choice depends on context. However, the verb number is wrong in both. For compound subjects joined by or (or nor), the verb agrees with the closer noun - here it's 'guide'. So the choices should be:

a) was ever seen
b) has ever been seen

For 2, the sentence is unclear. 'Either' is the subject and that's sigular, so the verb should be 'is', but the sentence itself does not make sense.

Answer 4

a or b is okay, but you have to add the word "again" after either choice. I personally prefer the (a) choice.

#2 is wrong.
Are you saying
Either one of my parents will have to leave our home"?
or
Neither one of my parents is to leave home?

or what?
I can't tell what you want to say. You have to explain a little more.
