Which of the following nouns may seem singular, but is used in plural sense?

A part of the sentence used to identify a person, place, animal, or thing is called a noun. A noun can be singular or plural, based on the number of nouns and pronouns used in the sentence. There are a few nouns that may seem singular but are always used in the sentence in a plural sense. A few examples are government, people, cattle, and mankind. Other options are incorrect as plural forms can be made of those words by adding 's'.
