When u got it wrong and you see the answer you caan memorize that answer and use it for the same question and you should get it right. But if you didnt just keep trying. Thats my advice
"The", "this" and "that" are all examples of definite articles. Definite articles introduce a SPECIFIC noun. "A" and "an" are examples of indefinite articles. Indefinite articles introduce NON-SPECIFIC nouns. "A woman" (non-specific noun) is eating (action verb) the rice (specific noun).
