Nouns that end on -ics can accept either a singular (if they are considered the noun of a science) or a plural verb (if they express a specific application of science): and finally, creating a question sometimes leads the subject to follow the verb. Identify the subject here, then select the verb that conforms to it (singular or plural). However, instead of using two sentences (as above), we may choose to give the above information in a single sentence. So there are three important topics – the rules of verb arrangement that should be remembered when a group element is used as a subject: collective nouns are nouns that refer to more than one person/animal. These are singular subjects, although they constitute a group. The following words are considered as crazy subjects, although they end with -s: short stories, thesis, hypothesis, crisis, analysis, politics, physics, mathematics, economics, ethics, athletics, etc. Some words seem plural, but actually come directly from other languages where s does not designate a plural form at the end of a word. . . .
