Question

Q.4 Grandpa claims that Martian
measles _______ green and
purple spots to erupt all over a
person's body.​

Answer 1

The correct answer for the given blank in the sentence is as follows:-

Grandpa claims that Martian  measles has green and  purple spots to erupt all over a  person's body.​

• Singular and plural are two forms of words that are used to show the quantitative structure of a sentence.
• Singular is used for a single object whereas plural is used for multiple objects.
• Martian measles here is a single entity here so we use "has" instead of "have", which is used for plural.
