Explicação:

O uso dos artigos indefinidos a e an no inglês depende do começo da palavra que vem depois deles: se a palavra começar com uma consoante, usa-se o a. Por exemplo:

• I have a new car
• My friend bought a colorful dress

Contudo, se a palavra se inicia com uma vogal ou com uma consoante com som de vogal, então usa-se o an. Exemplos:

• The agent saw an FBI memo on his desk
• The cherokee are an indigenous people of the USA

Embora "FBI" comece com uma consoante, se usa an por causa do som do F, "eff".
