[　　] A． To inform readers of Cameron's adventure to the Mariana Trench． B． To report on the successful launch of the “Deep-sea Challenger”． C． To introduce Cameron's latest video filmed in the Mariana Trench． D． To draw public attention to the Mariana Trench． (2) It can be inferred from the passage that when Cameron reached the Mariana Trench, ________． [　　] A． he felt worried and isolated B． he was anxious about his safety C． he was surprised by what he experienced D． he was excited that he had occupied the ocean (3) How does the “Deep-sea Challenger” differ from ordinary submarines?
