The recent discovery of a new species of dinosaur, which has been named *Dreadnoughtus* by paleontologists, is particularly exciting because it is one of the most complete skeletons of a dinosaur ever found. The skeleton, discovered in Patagonia, Argentina, includes much of the animal’s skull, neck, back, tail, and legs, and it is estimated to have been about 85 feet long and 65 tons in weight. Such a large dinosaur has never been discovered before.
Which choice provides the best way to combine the sentences at the end of the passage into a single sentence?
Correct answer: C
Explanation
Choice C is the most effective way to combine the two sentences because it uses a coordinating conjunction ("because") to join the two clauses, creating a grammatically correct and clear sentence. The phrase "such a large dinosaur has never been discovered before" is a nonessential clause that provides additional information about the excitement of the discovery. It is set off with commas, which is the correct punctuation for a nonessential clause.
