Hi @RJeh, thanks for your post. These sentences are not "all/none" statements, and are also not "most" statements. If you wanted to diagram "typically" or "tend to," you'd use "some":
CHE-some-PJO
CHTB-some-CHE

But you cannot combine two "some" statements into a transitive statement, so diagramming here does not do you much good.

Instead, you need to focus on the content of the stimulus, and follow along with its reasoning. The question stem here indicates that this is a parallel reasoning question, so you need to select the answer choice that most closely parallels the stimulus.

The stimulus contains an argument, the conclusion of which is "those in search of jobs should move to a city with high-tech businesses." Why? Because cities with high-tech businesses tend to have healthy economies, and cities with healthy economies tend to have plenty of job openings.

Answer choice (C) parallels this reasoning. Its conclusion is "those collectors who want antiques that are valuable should purchase their antiques from antique dealers." Why? Because antique dealers generally carry antiques that have had their ages authenticated, and antiques that have had their ages authenticated tend to be valuable.

Hope this helps. Please let us know if you have any additional questions!
