显示答案
D. damit
Rule: 'damit' introduces a purpose clause with its own subject and the verb at the end: '…, damit seine Nieren gut arbeiten können.' 'um' must be followed by 'zu' + infinitive and cannot have a separate subject. 'weil' gives a reason, but working kidneys are the goal, not the cause of drinking. 'deshalb' is an adverb meaning 'therefore' and needs the verb directly after it.
