The answer to your question would be that the sentence that correctly uses an MLA in-text citation is the following one: Research done by fish biologist Sarah Myers suggests that 25 percent of the carp are carriers of the vius (25). That is, the correct option would be A.
In MLA, you refer to other texts by using parenthetical citation. In this way, relevant source information is between parentheses whenever a sentence uses a quotation or paraphrase. Usually, this is done by putting all the relevant information in parentheses at the end of the sentence. The information to be included should be the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text. Therefore, the author's name must appear in the sentence itself or in parentheses following the quotation or paraphrase, but the page(s) number should appear in the parentheses, which is the case here.
(i’m assuming it’s supposed to be in first person, if it’s not you can just change the pov) To start my night time routine, I jump in the shower to rinse off after a long day. after that i get dressed into my pajamas for the night, usually an old t-shirt and a pair of sweatpants. after I get dressed i brush through my hair to get any tangled out, and head to the bathroom to brush my teeth. after flossing and gargling mouthwash, i go back to my room and double check to make sure i’ve done all of my homework that is due tomorrow. if i’m all caught up on my schoolwork, i go on my phone for a little bit, either scrolling through social media or texting friends. around eleven, i close my phone for the night and settle into bed, trying to get as much sleep as i can before my 6am alarm goes off.
hope this helps!
