Answer:
a) A or an Mr. Shah is _an_ artist.
b) Have you seen _the_ black onion?
c) _An_ unusual problem is driving us crazy.
d) Look, there is _a_ huge elephant coming towards us.
e) Simran is helping _the_ one-legged man cross the road.
f) France is _a_ European country.
g) He is _an_ outstanding actor.
Step-by-step explanation:
a) When using "a" or "an," it depends on the sound that follows the indefinite article. Since "artist" starts with a vowel sound (pronounced as "ar-tist"), we use "an" before it.
b) The word "black onion" refers to a specific onion, so we use "the" before it.
c) We use "an" before "unusual" because it starts with a vowel sound (pronounced as "un-yoo-zhual").
d) "Huge elephant" refers to a general elephant, so we use the indefinite article "a" before it.
e) Since "one-legged man" refers to a specific person, we use "the" before it.
f) "European country" is a general reference, so we use the indefinite article "a" before it.
g) We use "an" before "outstanding" because it starts with a vowel sound (pronounced as "out-stan-ding").
Remember, articles (a, an, the) are used to specify the noun's definiteness or indefiniteness. "A" or "an" are indefinite articles used for nonspecific or general reference, while "the" is a definite article used for specific or known reference.
