If the letter you are referring to is the one you get when you have your credit card account or bill delivered to your home, then the best answer would be most likely the second one. The letter provides the recipient information about the condition of his own bank account.
The sentence that accurately describes the relationship between the theory of Universal Grammar and the acquisition of a second language is "The theory of Universal Grammar supports language acquisition because all languages share a similar structure." According to this theory, there are <u>universal principles</u>, shared by all languages, and <u>parameters</u> that can vary between languages. So, a second language learner has to set the values of a parameter. For example, the pro-drop parameter has two values, the pro-drop in the case of the Spanish language, in which a subject or object pronoun can be omitted, and the non-pro drop in the English language, in which the pronoun cannot be omitted.
