Concept:The missing word must contrast with “temporal,” meaning worldly, material, or temporary.
Explanation:“Temporal” refers to things that pass with time or belong to ordinary material life.
The phrase “to the detriment of” shows that this focus harms or neglects another area.
The strongest opposite idea is “spiritual,” which relates to the soul, faith, or eternal concerns.
“Tangible,” “durable,” and “unchanging” do not carry that same meaningful contrast here.
Therefore, the sentence means people care too much about temporary matters and neglect spiritual ones.
Answer:D. spiritual
