Odd Sentence Out 2 / 54

The following five sentences, labeled 1 to 5, relate to a single topic. Four of these sentences can be arranged to form a logical paragraph. Identify the sentence that does not fit with the others and enter its number as your answer.

1. The burgeoning field of germline editing presents a profound ethical quandary, blurring the lines between ameliorating debilitating inherited diseases and the aspiration for genetic 'enhancements' beyond therapeutic intent.
2. This distinction is crucial, as the pursuit of 'designer babies' could entrench a new form of biological stratification, where access to genetic advantages becomes a privilege of the affluent.
3. Despite significant theoretical advances, the precise control and off-target effects of CRISPR-Cas9 technology in human embryos still pose considerable technical hurdles, making widespread, predictable genetic enhancement a distant prospect.
4. Such a scenario risks exacerbating existing socio-economic disparities, creating a biologically divided society where genetic 'perfection' is attainable only by a select few, thus undermining fundamental principles of equality.
5. Consequently, critics warn of a potential "slippery slope" towards a eugenic future, where societal pressures might compel parents to seek enhancements, transforming genetic diversity into a perceived deficiency.

Correct Answer: 3
Identification of the Theme: The core argument revolves around the ethical and societal implications of genetic engineering and the pursuit of 'designer babies', particularly concerning social stratification, inequality, and the risk of eugenics.
Logical Sequence of the Coherent Paragraph: 1-2-4-5.
Sentence 1: Introduces the central ethical dilemma regarding the distinction between therapeutic genetic editing and genetic enhancement.
Sentence 2: Explains how the pursuit of genetic enhancements, or 'designer babies', could lead to a new form of social stratification based on economic access.
Sentence 4: Elaborates on the consequences of this stratification, describing a divided society that undermines principles of equality.
Sentence 5: Concludes by presenting the "slippery slope" argument, warning of the potential for a eugenic future driven by societal pressures for enhancement.
Why Sentence 3 is the Odd One Out: While Sentence 3 is topically related to genetic engineering, it shifts the focus from the ethical, social, and philosophical implications of genetic enhancement (the core theme) to the current technical challenges and limitations of the technology itself. The other four sentences discuss the *consequences and ethical dilemmas* of such interventions if they were widely available and effective, whereas Sentence 3 addresses the *practical feasibility* of achieving widespread genetic enhancement at present.
