I immediately wondered the same thing. An example from their questions was:

Q: "Which word contains “z” from the list: zoologist, midwifery, spiderweb, crimps?" A: "zoologist"

But what if you change up that list a bit?

Q: "Which word contains “z” from the list: action, jackson, midwifery, zoologist, spiderweb, crimps?" A: "jackson"

Alpha's sentence digestion has always left me going: huh?
