a / an
the / a
the / an
Correct Answer: EASY
“The” is used before words: first, second,…, only….
“A” and “An” are used to introduce the first thing mentioned to the listener (the listener does not know anything about this). However, use “An” when the following letter begins with a vowel (a, o, ue,i) and use “A” when the following letter begins with the remaining consonants.
Translated: Prince Harry will become the first member of the British Royal family to marry an American actor.
