Science teacher: In any nation, a flourishing national scientific community is essential to a successful economy. For such a community to flourish requires that many young people become excited enough about science that they resolve to become professional scientists. Good communication between scientists and the public is necessary to spark that excitement.

Summary

If a nation has a successful economy, it must have a flourishing national scientific community. If the nation has a flourishing national community, it needs to have many young people who are excited enough about science to want to become scientists. If this excitement exists, there must be good communication between scientists and the public.

Strongly Supported Conclusions

Successful economy -> flourishing scientific community -> young people excited - > good communication between scientists and the public.

You can make any valid inference along this chain.

A
If scientists communicate with the public, many young people will become excited enough about science to resolve to become professional scientists.

Scientists communicating with the public is not a sufficient condition that can trigger any valid inferences. If you got this wrong, practice conditional indicators, mapping, and following lawgic chains.

B
The extent to which a national scientific community flourishes depends principally on the number of young people who become excited enough about science to resolve to become professional scientists.

While young people's excitement about science is necessary for a national scientific community to flourish, there is no evidence that *the number* of these students is principally important.

C
No nation can have a successful economy unless at some point scientists have communicated well with the public.

This is supported because it is a valid inference on the formal logic chain (Successful economy -> good communication). If you struggled to map this, practice mapping with two conditional indicators.

D
It is essential to any nation’s economy that most of the young people in that nation who are excited about science become professional scientists.

This is too strong to support. The stimulus only says that many young people need to be excited about science, not “most.”

E
An essential component of success in any scientific endeavor is good communication between the scientists involved in that endeavor and the public.

This is not supported because the stimulus never gives conditions for the success of any scientific endeavor.
