question: scalpel:surgeon

choices.text: fishing nets:fishermen podium:teacher lighter:smoker telescope:scientist
explanation: the tool used by a "surgeon" to perform an operation is a "scalpel" the tools used by "fishermen" to fish are "fishing nets". "teachers" do not necessarily need to give lectures on the "podium", and "podiums" are places for "teachers" to teach instead of tools. the tool a "smoker" needs to smoke is a "lighter", but a "smoker" is not a profession. a "telescope" is an astronomer's tool, not a "scientist" tool.
