I'll gladly check your answers.

I got C for the first one and D for the second

Yes. Both answers are right.

To effectively combine the two sentences "The plainer rooms are more sparsely furnished" and "Their architectural features, furnishings, and decorations are just as true to the periods they represent," you can use the coordinating conjunction "but" to show contrast.

So, the correct choice is C. The plainer rooms are more sparsely furnished, but their architectural features, furnishings, and decorations are just as true to the periods they represent.

For the second question, the sentence "It took the camp counselors over an hour to find Tanya, who will hide beneath the canoes after listening to the scary ghost story," is incorrect.

To correct this sentence, you should change "will hide" to "had been hiding" to indicate that Tanya had been hiding under the canoes in the past tense.

Therefore, the correct choice is D. Change "will hide" to "had been hiding."
