Question

article you must fight _ hero​

Answer 1

Sentence given with a blank:

You must fight ___ hero.

$\bf\pink{What \: to \: do? }$

→ Fill the blank with appropriate article.

$\bf\blue{What \: to \: insert?}$

→ A appropriate preposition (words that relate nouns and pronouns with other nouns and pronouns).

Answer:

You must fight with hero.

$\Large\mathbb\pink{HOW?}$

→ As there is a blank that doesn't relate the word hero in the sentence, so we need a word that should relate hero with the sentence given. So, words that relate nouns and pronoun with other noun and pronoun is called a preposition.So, we used here with.

Thus, we filled the blank with correct and appropriate parts of speech.

$\rm\blue{So,done!}$

Answer 2

$\large\underline\mathbb\purple{QUESTION}$

Insert articles (a, an, the) in the blank:

→ You must fight ____ hero.

$\large\underline\mathbb\purple{ANSWER}$

We cannot insert an article in the blank because any of the words– 'a', 'an' or 'the' doesn't suit/fit in the blank. So we can insert an appropriate preposition to make the sentence meaningful.

→ You must fight with hero.

Now, we have inserted the preposition "with" in the blank which makes a sense.
