Final answer:
The best fit for the blank in the sentence '_________ went to baseball practice together today.' is 'We', as 'We' is the only plural subjective case pronoun among the options that agrees with the plural action in the sentence.
Step-by-step explanation:
The sentence “_________ went to baseball practice together today.” requires a subject that matches the verb in number. Here, the verb 'went' indicates that the subject needs to be plural to denote that more than one person participated in the activity. As a result, the best fitting option from the provided choices for the blank is 'We'. Therefore, the complete sentence is: “We went to baseball practice together today.” This demonstrates what is known as pronoun-antecedent agreement, which means using a pronoun that correctly corresponds to the number and person of the noun it is replacing or referring to.
In this case, 'We' is a subjective case pronoun that functions as the subject of the sentence and agrees with the verb 'went'. It is important to note that 'I', 'He', 'You' are all singular subjective case pronouns and would not fit the plural context of the sentence. Incorrect use of these pronouns would lead to a pronoun-antecedent number agreement error.
Understanding the concept of pronoun-antecedent agreement is essential in constructing grammatically correct sentences. When choosing a pronoun to complete a sentence, it's important to ensure that it matches the singular or plural form and gender (if applicable) of the noun to which the pronoun refers.
