Answer:'Sews' is used in the plural form.
Explanation:Words like athletics, politics, and news are used in this form as these are their original forms. Moreover, these are all nouns that are plural in form but are singular in construction. Additionally, removing the 's' from the end would yield a word that bears an altogether different meaning.
- 'Athletic' is an adjective that means anything that relates to the athletes or the domain of athletics
- 'Politic' is an adjective that means someone that shows shrewdness.
- 'New' is an adjective that means something that has only recently come into existence.
However, the singular form of 'sews' is 'sew' and they are both verbs bearing the same meaning. Thus 'sews' is in the plural form.
