Объяснение:
"A" ставится, когда идёт речь об единственном числе и о том, что можно сосчитать (пример: a kid)
"An" так же, как и "A", но ставится когда существительное начинается с гласной (an orange)
"Some" ставится, когда идёт речь о множественном числе, а также о том, что нельзя посчитать (пример: some rice (нельзя рис посчитать поштучно; some T-shirts (несколько футболок))
