If the subjects are joined by ¡°nor¡± or ¡°or,¡± the verb agrees with the closer subject (the last one).

1. Either you or I _____ to go there. (be)
2. Neither the prices nor the quality _____ changed. (have)

(Explanation) In Sentence 1, the personal pronouns are joined by or. In this case the verb agrees wth the colser pronoun. I is the first person singular, so you should use the singular verb am in the blank.

In Sentence 2, two subjects are joined by nor. In this case, the verb agrees with the closer subject. As the closer subject is the quality, you should use the singular auxuiary verb has in the blank. In the parentheses, there is a base verb. Change have into has,and wite have in the blank.

Thank you for your help. Would you take a look at the expressions above? I'd like you to let me know some grammatical errors in them.

p.s. If I want to make a word in Italic, what do I have to do when I post the mesage?

Your answers are exactly correct.

In the first answer "sentence" does not need to be capitalized. I would put "or" ,"I", "am" to designate you are quoting from the previous sentence. "Closer", "write" and "auxiliary" are mispelled. For the last sentence, I would just write - Write "has" in the blank.

In order to use italics -
will make the word into italics.
will remove the italics.

In sentence 2, again, "nor", "quality", "has". You do not need the sentence - In the parentheses, there is a base verb.

oppppssss! to make italics use < then put i and then use>

to close italics, use <, /, i, > but don't put the commas in.

And the second paragraph should read:
In sentence 2, again, "nor", "quality", "has". You do not need the sentence - "In the parentheses, there is a base verb."
For the last sentence, I would just write - Write "has" in the blank.

There are a few grammatical errors in the expressions provided. Here are the corrections:

1. In Sentence 1, the verb "be" should be in its base form, not the singular form "am". So the correct verb to use in the blank is "be."

2. In Sentence 2, the auxiliary verb "have" should be in its base form because of the word "neither" - which is used to negate two options. So the correct verb to use in the blank is "have."

Regarding making a word italic when posting a message, it depends on the platform or medium you are using. In most cases, you can surround the word with asterisks (*) or underscores (_) to italicize it. For example, *italic* or _italic_. However, different platforms may have their own formatting options, so it's best to consult the specific guidelines or formatting options available on the platform you are using.
