Which of the following options is a correct plural spelling?

 

Choice C, "plumb," is the appropriate word here. It means to measure the depth of something or to explore thoroughly, which fits the context of the sentence.

It describes a virtual image of the Ferris wheel, which is a common feature of county fairs.

One should check for punctuation errors to ensure no grammar errors in their writing.

Choice B is correct, as explained below.
"I plan to enroll in College next year" incorrectly capitalizes the word "College." The general rule for capitalization is that common nouns, such as "college," should not be capitalized unless they are part of a proper noun or a specific institution's name.

Corrected, the sentence would be: "I plan to enroll in college next year." Kindly note that the question asks for the incorrectly capitalized sentence.

The other choices are wrong as below:

Choice A: The Geography students took a class trip to the Rocky Mountains.

• This sentence correctly capitalizes "Geography" because it is the name of a specific subject or course. "Rocky Mountains" is also capitalized because it refers to a proper noun (a specific mountain range).

Choice C: Even though he moved to New York, he was born in a Western town.

• "New York" is correctly capitalized as it is the name of a specific state. "Western" is capitalized because it is part of the proper noun "Western town" which refers to a specific town in the Western region.

Choice D: The A1 Plumbing Board of Directors gave every employee a raise.

• "A1 Plumbing Board of Directors" is a specific organization's name, so all parts of it are capitalized appropriately.

Choice C: "However"

The sentence suggests a contrast or contradiction between the extensive responsibilities of a class president and the need not to neglect her studies. "However" is a transitional word that effectively introduces this contrast or counterpoint, making it the most suitable choice to complete the sentence.
