Explanations:Phrasal verbs are a combination of a verb and a particle (adverb or preposition) that together have a specific meaning. In the context of the question, "washes up" is a phrasal verb that means to clean oneself, typically after a meal or before bed. The phrasal verb "wash up" is separable, meaning the object can be placed between the verb and the particle, but in this case, there is no object, so the verb and particle remain together.
The question requires the use of the simple present tense, which is used to describe habitual actions or general truths. In the simple present tense, the verb form changes based on the subject. For third-person singular subjects (he, she, it), the verb takes an "-s" or "-es" ending. For example, "he washes," "she washes," "it washes." In the given sentence, "Emilia" is a third-person singular subject, so the verb "wash" must be conjugated to "washes."
Option A, "Washes up," is the correct answer because it correctly conjugates the verb "wash" to "washes" to agree with the third-person singular subject "Emilia." The particle "up" remains attached to the verb, forming the complete phrasal verb "washes up."
Option B, "Wash ups," is incorrect because it does not conjugate the verb "wash" to agree with the subject "Emilia." The correct form would be "washes," not "wash."
Option C, "Wash up," is incorrect because it uses the base form of the verb "wash" without the necessary "-s" ending for the third-person singular subject "Emilia."
Option D, "Is wash up," is incorrect because it incorrectly uses the present continuous tense instead of the simple present tense. The correct form in the present continuous tense would be "is washing up," but the question requires the simple present tense.
Understanding the correct usage of phrasal verbs in the simple present tense is crucial for constructing grammatically correct sentences. It is important to remember that the verb must agree with the subject in terms of person and number, and the phrasal verb should remain intact unless there is an object that can be placed between the verb and the particle.
