问题 By introducing the theory of red giant, the author intends to ______
When our Sun dies, it may ______

选项 A、shed most of its mass to the space and shrink into a dwarf directly.
B、break up into pure water and sand.
C、blow its transparent outermost layer into space by starlight.
D、bloat to a red giant and make carbon from pitch-black dust.

答案D

解析为推理判断题。A选项不符合文中的描述，应当先成为红巨星再变成白矮星。B中所提到的是太阳所释放的物质，但这应当是一个化合的过程而非分解。文中提到太阳的光线可以直接穿过透明的外部物质，因此C也不准确。D为文章原文，故选D。
