Step 1: Extract given facts.
- Pacific yew grows in the Pacific Northwest.
- It produces fleshy fruit that is poisonous.
- Its bark contains taxol, a promising anticancer drug.
Step 2: Evaluate the options.
(a) Not stated. We only know taxol is promising as a drug, not that it is poisonous.
(b) Correct. The fruit is explicitly described as poisonous, so people should not eat it.
(c) Not stated. It is only "promising," not proven to have cured diseases yet.
(d) Not stated. Nowhere is it mentioned that the tree was considered worthless before taxol. \[ \Rightarrow \boxed{\text{(b) People should not eat the fruit of the Pacific yew.}} \]
