INDICATE THE FUNCTION OF THE UNDERLINED NOUNS IN THE FOLLOWING SENTENCES.

1. THE CLASS DISCUSSIONS IS ON THE PREVENTION OF DISEASES. THE UNDERLINED IS DISEASES
2. MARIE STEPHEN ADMINISTERED INJECTION TO HER PATIENT. THE UNDERLINED IS INJECTION

(Please release your Caps Lock key. When you type in all-caps online, it's considered shouting -- and sometimes it's considered rude.)

Basic English word order is this:
subject -- verb -- direct object
(John hit the baseball.)

Variations are these:
subject -- linking verb -- predicate noun or adjective
(James is a repairman.)

subject -- passive verb -- prepositional phrase
(The ball was hit by John.)

In addition to these basics, there can be all kinds of adjectives, adverbs, and phrases (and other clauses) to give more detail to the sentence.

#2 of your sentences is quite easy. Look at the very first example (basic English word order) that I gave you.

#1 has an error. It should probably be "The class discussion is on the prevention of diseases."

To determine the function of the underlined nouns in the given sentences, we need to identify the grammatical role they play in the sentence structure.

1. "The class discussions is on the prevention of diseases." - The underlined noun is "diseases."
In this sentence, "diseases" functions as the object of the preposition "of." It shows what the prevention is focused on, indicating the topic of the discussions.

2. "Marie Stephen administered injection to her patient." - The underlined noun is "injection."
In this sentence, "injection" functions as the direct object of the verb "administered." It receives the action of the verb, showing what Marie Stephen administered.

In both cases, understanding basic English sentence structure and identifying the verb and its complement (direct object or object of the preposition) allows us to determine the function of the underlined noun in each sentence.
