问题 The primary purpose of the passage is to______
According to Snyder et al, all of the following compounds can bind to specific receptors in the brain EXCEPT______

选项 A、IBMX
B、caffeine
C、adenosine
D、theophylline
E、phosphodiesterase

答案E

解析 E is the best answer. This question asks you to identify which compound, according to Snyder et al, does NOT bind to specific receptors in the brain. Phosphodiesterase, identified as an “enzyme that breaks down the chemical called cyclic AMP”(lines 40-42), is the only compound that is not identified as one that binds to specific receptors in the brain.
