The main clause is “Attendees of the marketing convention were assured something,” ending with a noun clause that starts with the word “that” and continues to the end of the question to explain what is assured. </span></p><br><p dir="ltr" style="line-height:1.2;text-align: justify;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">The noun clause itself is a complex sentence too. In this noun clause, the main clause is “_______ report could be provided,” embedded with a short adjective clause “they needed” to modify the noun “______ report.” And the noun clause itself ends with a phrase starting with “if.” </span></p><br><p dir="ltr" style="line-height:1.2;text-align: justify;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">Let’s focus on the main clause of the noun clause, “________ report they needed could be provided.” The phrase “_______ report they needed” serves as the subject of this main clause, and the blank should be filled with a compound relative pronoun that means “</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">any one that</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">,” and the word “one” can be replaced by any noun after the compound relative pronoun, like the noun “report” in this main clause. Moreover, the context indicates that the noun after the compound relative pronoun would be one of the limited options. After all, the attendees wouldn’t need any kind of report available in the world. They would only need a particular kind of reports about marketing. </span></p><br><p dir="ltr" style="line-height:1.2;text-align: justify;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">Only Choice (B) </span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-style: italic; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">whichever</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> can serve this function. If it’s filled into the blank, the phrase “whichever report” means “any report that,” and the main clause of the noun clause will mean “</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; text-decoration-line: underline; text-decoration-skip-ink: none; white-space-collapse: preserve;">any</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> report </span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; text-decoration-line: underline; text-decoration-skip-ink: none; white-space-collapse: preserve;">that</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> they needed could be provided.” This is a grammatically correct clause and fits the context. </span></p><br><p dir="ltr" style="line-height:1.2;text-align: justify;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">In comparison, Choice (C) </span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-style: italic; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">whatever</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> is not as appropriate as Choice (B) </span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-style: italic; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">whichever.</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> It’s true that the word “whatever” can also serve as a compound relative pronoun that means “anything that,” and can be followed by any noun or noun phrase that refers to something. But the noun after it would be one of the unlimited options, which doesn’t fit the context very well. </span></p><br><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">Choice (A) </span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-style: italic; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">whenever</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> and Choice (D) </span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-style: italic; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;">wherever</span><span style="font-size: 14pt; font-family: "Times New Roman", serif; color: rgb(0, 0, 0); font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; white-space-collapse: preserve;"> are adverbs and can’t be followed by a noun. Besides, they respectively mean “at any time” and “at any place,” and neither of the meanings fit the context of the noun clause at all. </span></span>
