Write the correct article to complete the sentence.

They adopted ___ cat from the shelter.

Answer explanation

The correct article is "a" because "cat" starts with a consonant sound (/k/). The rule is the same: we use "a" before words that begin with a consonant sound and "an" before words that start with a vowel sound. Since "cat" begins with the consonant sound /k/, "a" is the correct choice.

​ (a)   car​
(b)   elephant

(c)   house

​ (d)   opinion

• a
• an
• one
• two

Which article is correct in this sentence:
"I need ___ hour to finish my homework."

• an
• some
• one
• the

Answer explanation

The rule for using "a" or "an" depends not on the written vowel or consonant but on the initial sound. In this case, "hour" is pronounced /ˈaʊər/, without an "h" sound at the beginning, so it sounds as if it starts with a vowel.
