To solve this problem, we need to identify the sentence that does not fit into the sequential flow of a coherent paragraph. Let’s analyze each sentence:
This sentence introduces the general apprehension about genetic engineering and sets the tone for the ethical questions that follow.
This sentence discusses the dual implications of genetic breakthroughs — preventing diseases and enhancing genetic traits — both of which are key ethical concerns.
This sentence introduces the difficulty of addressing the ethical concerns surrounding genetic enhancement, linking them to theology and philosophy.
This sentence provides a specific ethical objection to genetic enhancement, focusing on the idea of mastery and human limitations.
This sentence shifts the focus to a more general discussion about the role of philosophers in assessing moral arguments, which is not directly tied to the discussion of genetic enhancement.
While sentences 1-4 discuss the ethical issues surrounding genetic engineering and enhancement, sentence 5 diverges by focusing on the general philosophical approach to biotechnology rather than the specific debate on enhancement. Therefore, sentence 5 does not fit in the sequence.
The sentence that does not fit is:
"The care with which philosophers examine arguments for and against forms of biotechnology makes this an excellent primer on formulating and assessing moral arguments."
For any natural number $k$, let $a_k = 3^k$. The smallest natural number $m$ for which \[ (a_1)^1 \times (a_2)^2 \times \dots \times (a_{20})^{20} \;<\; a_{21} \times a_{22} \times \dots \times a_{20+m} \] is:
