Çözüm: Paragrafta ateş böceğinin eş çekmek, fener balığının avlanmak için ışık ürettiği anlatılmış; son cümlede ise "Whether for finding a partner, hunting, or evading capture..." denilmiştir. Partner bulma ve avlanma yukarıda anlatıldığına göre, avcılardan kaçma (evading capture) örneği boşlukta olmalıdır. D şıkkında mürekkep balığının avcılardan kaçmak için ışıklı mürekkep püskürtmesi tam bu işlevi tamamlar.
