5. Which of the following sentences would best be inserted between sentences 11 and 12?
Answer: B
This rather implausible conclusion nonetheless persisted for years.
Inserting this sentence between sentences 11 and 12 effectively transitions from the long-standing belief about sauropod growth rates to the new findings that challenge that belief. It highlights the persistence of outdated assumptions in scientific research, setting the stage for the subsequent revelation about sauropod growth.
A) Like all dinosaurs, sauropods hatched from eggs.
This option, while true, does not relate to the discussion of growth rates and would not provide a relevant transition between the sentences. It does not address the implausibility of the previous growth rate conclusions, making it an unsuitable choice.
B) This rather implausible conclusion nonetheless persisted for years.
This statement directly addresses the flawed assumption regarding the growth rates of sauropods and emphasizes how deeply ingrained this misconception was among scientists. It is the most fitting choice because it connects the outdated belief to the subsequent analysis of sauropod bones, leading to the new understanding of their growth.
C) For decades, sauropods were considered emblematic of the phenomenon of extinction.
While this statement provides historical context about sauropods, it does not specifically connect to the discussion about growth rates. It shifts focus away from the core topic, making it less relevant for insertion between the two sentences.
D) Sauropod fossils continue to be discovered in regions spread across the globe.
This option introduces new information about recent fossil discoveries but does not relate to the discussion of growth rates. It does not serve as a logical bridge between the two sentences, thereby making it an inappropriate choice.
Conclusion
The correct answer, "This rather implausible conclusion nonetheless persisted for years," effectively captures the essence of the historical misunderstanding regarding sauropod growth rates. It provides a necessary transition that acknowledges the long-standing nature of the misconceptions before introducing the new insights gained from studying their fossils. The other options fail to connect with the main theme of growth rates, making them less suitable for inclusion.
