The theme of the phrase is „the youngest girl,“ a single nostantiv. Although the verb is next to the plural „students,“ a verb, the verb must be a singular verb. In addition, a superlative must need a comparison to be used properly, so that „dark hair“ is the right answer choice. Replace the highlighted part by selecting answers that results in a clear and accurate set that meets the requirements of standard policing English. a physical or electronic signature of the copyright holder or a person authorized to act on his behalf; Identification of copyrights that have been infringed; A description of the nature and exact location of the content you claim to be infringing against your copyright, in sufficient detail to allow Varsity tutors to find and positively identify this content; for example, we need a link to the specific question (not just the name of the question), which contains the content and description, to which specific part of the question – an image, a link, the text, etc. – refers your complaint; Your name, address, phone number and email address; and a statement from you: (a) that you believe in good faith that the use of content you claim to violate against your copyright is not authorized by law or by the copyright holder or by the owner`s representative; (b) that all the information contained in your infringement communication is accurate and (c) perjury, whether you are either the copyright holder or a person authorized to act on its behalf. The simple theme of the sentence is „everyone,“ so the predicate must be singular instead of the plural. In this sentence, „Each student“ is the theme, so we need a unique predicate. The only choice of answers that contains a single predicate for the subject „Each of the students“ is „Each of the students was sick last week, so the professor canceled the conference.“ The verb in the sentence, written in the section emphasized as „face,“ must in fact be in the singular form of „faces.“ The theme of the phrase is „everyone,“ which is actually a singular form, although the verb sits next to „new coaches.“ „The new coach faces“ is the right answer.
