Answer:
Demonstrative Pronoun: "These"
Verbal: "earning"
Type of verbal: "gerund"
Personal pronoun: "my"
Step-by-step explanation:
Demonstrative Pronouns: These are the pronouns which point to something specific within a sentence
Examples: this, that, these, those, such, none, neither.
Verbals: These are words made from verbs but functioning NOT as verbs but as something else (nouns, adjectives, or adverbs).
Examples: In the sentences; cooking requires a lot of skill, he is a learned man, she likes to eat mangoes, cooking (gerund), learned (participle), and to eat (infinitive) are verbals.
Gerund verbal: These are verbals formed by adding -ing after the verbs and functioning as noun. "earning" is acting as a noun; and hence is a gerund.
The personal pronoun "my" is used modifying gerund (noun) "earning"
