The question involves inserting articles in the blanks. Articles are words that define a noun as specific or unspecific. In English, there are two articles: 'a/an' and 'the.' 'A' and 'an' are indefinite articles, used when referring to something nonspecific. 'The' is a definite article, used when referring to something specific.
Here's how you fill in each blank:
An empty vessel makes much noise.
Nobody likes a fair-weather friend.
Pride goes before a fall.
A stitch in time saves nine.
The early bird catches the worm.
An apple a day keeps the doctor away.
A bad man always quarrels with his tools.
A drowning man will clutch at a straw.
An army of sheep led by a lion would defeat an army of lions led by a sheep.
He gave an orange to the boy.
Her father gifted her an iPhone on her birthday.

Please give me a cup of coffee.
It was a rainy day, so I took an umbrella to go outside.
Understanding when to use 'a,' 'an,' and 'the' can help make writing clearer and more precise. Use 'a' before consonant sounds and 'an' before vowel sounds. 'The' is used when specifying a particular item that is known to both the speaker and listener.
