explanation: both "duty" and "responsibility" refer to things that should be done, which have similar meanings. both "fetters" and "obstacles" refer to restraints, which have similar meanings. "gem" is a metaphor for unusual and excellent literary and artistic works or very outstanding figures, having no obvious logical relationship with "treasure house". "blueprint" is a metaphor for schedules and planning, having no obvious logical relationship with "imagination". "pride" refers to arrogance, and "prejudice" refers to one-sided opinions. there is no obvious logical relationship between the two.
