Which sentence is correct? 1. There was a long line to see the play Aliens At School. 2. There was a long line to see the play "Aliens at School." 3. There was a long line to see the play Aliens at School.

Answer
The correct sentence is: 'There was a long line to see the play Aliens at School.' (where 'Aliens at School' is italicized). Explanation: 1. Formatting Titles: According to standard style guides (like MLA or Chicago), titles of major works such as plays, movies, and books should be italicized. Short works like songs or poems are typically placed in quotation marks. Since 'Aliens at School' is a play, it should be italicized rather than put in quotes. 2. Capitalization: In title case, you capitalize the first and last words and all principal words (nouns, pronouns, verbs, adjectives, adverbs). However, you should not capitalize articles (a, an, the), prepositions (at, by, for, in, etc.), or coordinating conjunctions unless they are the first or last word of the title. Therefore, 'at' should remain lowercase. Applying these rules, 'Aliens at School' (italicized with 'at' in lowercase) is the grammatically correct choice.
