问题 This______radiation would unavoidably have freed oxygen by decomposing the water vapor and carbon dioxide in the atmosphere.

选项 A、intensive
B、weighty
C、bulky
D、intense

答案 D

解析这句话的意思是：这种强烈的紫外线辐射，将不可避免地通过分解大气中的水蒸气和二氧化碳释放氧气。intense意为“强烈的、剧烈的”；intensive意为“加强的、集中的”；weighty意为“沉重的、笨重的”；bulky意为“庞大的、粗壮的”。根据题意，答案为D。
