1. Microplastics are tiny plastic particles that can enter the environment as larger plastic products break down.
2. Recent studies indicate that ingestion of common microplastic particles alters cellular function and that these alterations are associated with medical conditions including respiratory issues, reproductive failures, and immune system deficiencies.
3. These synthetic particles are termed "perpetual pollutants" because they do not organically degrade in marine ecosystems.
4. The investigations might also reveal additional illnesses potentially triggered by microplastics that have not yet been documented.
5. The results represent a crucial advancement in understanding the biological pathway through which these particles trigger illness and could assist physicians in diagnosing, screening, and managing health issues for individuals exposed to microplastics before symptoms worsen.
Q12. Identify the odd sentence out and key in its number.
Answer and solution
Correct answer: 3
Solution
1. Sentence 1 introduces the substance being discussed. Sentence 2 introduces research into human health effects.
2. Sentence 4 continues the investigations and additional illnesses. Sentence 5 explains the clinical importance of the results.
3. These four form a definition → research → further findings → medical application progression.
4. Sentence 3 concerns persistence in marine ecosystems and does not develop the health-research thread.
5. Answer: 3; a coherent retained order is 1–2–4–5.
Detailed reasoning and elimination check:
The retained sentences share a research-and-health function, not merely the word microplastics. Sentence 3 is scientifically themed background about persistence in marine environments, while 2,4,5 develop findings, further disease research and clinical use. Its thematic role makes it the odd sentence.
