1. In context, which is the best way to revise and combine sentences 1 and 2?
Answer: A
The fossils of sauropods, the long-necked giants who are known today as the largest dinosaurs, have baffled scientists for decades.
This revision effectively combines the essential elements of the original sentences while enhancing clarity and flow. It establishes the identity of sauropods as the long-necked giants and succinctly states the baffling nature of their fossils.
A) The fossils of sauropods, the long-necked giants who are known today as the largest dinosaurs, have baffled scientists for decades.
This option is correct as it successfully integrates both sentences, maintaining the critical information about sauropods being the largest dinosaurs and the confusion their fossils have caused scientists. The structure is clear, and the sentence reads smoothly.
B) Sauropods, long-necked giants, are known today as the largest dinosaurs whose fossils have baffled scientists for decades.
While this option conveys the same information, it uses "whose fossils" in a way that may imply a weaker connection between the giants and the baffling nature of their fossils. The phrasing feels slightly awkward compared to the clarity of option A.
C) Scientists have been baffled for decades by sauropod fossils; they are known today as the largest dinosaurs, being giants with long necks.
This choice introduces a passive voice and a more complex structure that detracts from the directness of the original sentences. It splits the information into two clauses, which can diminish the impact and clarity of the statement.
D) [no change]
Selecting no change does not improve the original sentences, which could benefit from a more effective combination for clarity and fluidity. The original sentences are somewhat disjointed and could be more cohesively expressed.
Conclusion
Option A is the best revision as it seamlessly combines the key ideas about sauropods while enhancing readability. The other options either convolute the message or fail to achieve the same level of clarity and cohesion, making A the superior choice for effectively communicating the information.
