Complete the paragraph with the most appropriate option:
In evolutionary biology, "island gigantism" describes the phenomenon where small mainland species evolve to significantly larger sizes after colonizing isolated oceanic islands. Free from continental mammalian predators and facing competition for limited food niches, smaller animals often expand in bulk over generations. ---- The giant tortoises of the Galapagos Islands and the extinct dodo of Mauritius represent famous historical examples of this dramatic evolutionary trend.

- A)Conversely, large animals often undergo island dwarfism due to restricted food resources.
- B)Larger body dimensions provide greater metabolic efficiency and resilience against famine.
- C)Human colonizers introduced invasive rats and pigs that devastated endemic island wildlife.

Doğru cevap: B) Larger body dimensions provide greater metabolic efficiency and resilience against famine.
Çözüm: Metinde küçük canlıların adalarda neden devleştiği (island gigantism) açıklanmaktadır. B seçeneğindeki "Larger body dimensions provide greater metabolic efficiency and resilience against famine" (Daha büyük vücut boyutları açlığa karşı direnç ve metabolik verimlilik sağlar) ifadesi bu evrimsel avantajı açıklar ve ardından Galapagos kaplumbağaları örneğine bağlanır.
