Explanations:Coordinating conjunctions are a fundamental part of English grammar, used to connect words, phrases, or clauses of equal importance. The acronym FANBOYS (For, And, Nor, But, Or, Yet, So) is a mnemonic device that helps remember these conjunctions. Each of these conjunctions serves a specific purpose in forming compound sentences.
In the context of the question, we are asked to combine two positive statements about Nam: "Nam is diligent" and "Nam studies very well." The goal is to form a compound sentence that maintains the positive nature of both statements. The correct conjunction to use in this case is "And," which is used to connect two positive statements without implying any contrast or choice between them.
Let's examine the role of each coordinating conjunction in more detail:
And: This conjunction is used to add information or combine two positive statements. It is the most straightforward of the FANBOYS conjunctions and is used when both parts of the sentence are equally important and positive. For example, "Nam is diligent and Nam studies very well" combines two positive attributes of Nam without any contrast or choice.
But: This conjunction is used to introduce a contrast or exception to the first part of the sentence. For example, "Nam is diligent but does not study well" would imply that despite Nam's diligence, there is a negative aspect to Nam's study habits. This does not fit the context of the question, as both statements are meant to be positive.
Or: This conjunction is used to present a choice or alternative between two options. For example, "Nam studies very well or Nam is diligent" would imply that Nam has to choose between being diligent or studying well, which is not the intended meaning of the original statements.
For: This conjunction is used to introduce a reason or explanation for the first part of the sentence. For example, "Nam studies very well for Nam is diligent" would imply that Nam's diligence is the reason for Nam's good study habits. While this could be a valid sentence, it does not directly combine the two positive statements as a single idea.
Nor: This conjunction is used to add a negative statement to another negative statement. For example, "Nam is not diligent nor does Nam study well" would imply that Nam lacks both diligence and good study habits, which contradicts the original positive statements.
Yet: This conjunction is used to introduce a contrast or unexpected result. For example, "Nam is diligent yet does not study well" would imply that despite Nam's diligence, there is an unexpected negative aspect to Nam's study habits, which again contradicts the original positive statements.
So: This conjunction is used to introduce a result or consequence. For example, "Nam is diligent so Nam studies very well" would imply that Nam's diligence leads to good study habits, which is a valid sentence but does not directly combine the two positive statements as a single idea.
In conclusion, the correct answer is "Nam is diligent and Nam studies very well" because it uses the conjunction "And" to combine two positive statements about Nam without implying any contrast or choice between them. This maintains the positive nature of both statements and forms a coherent compound sentence.
