- Exemption: Privilege
If someone is exempted from paying for admission to a concert that could be considered a privilege.
- Reading: skill
Reading is considered to be a skill as it has to be learned. No one is born with this ability.
- Shiftless: objective
Someone who is shiftless has no plan in life and is usually considered lazy.
Someone who has an objective in life (or a plan) could be considered to be a person possessing characteristics that that are the OPPOSITE of a shiftless person.
- Callous: sympathy
If someone commits a callous act they are showing themselves to possess a characteristic that is the OPPOSITE of sympathy.
So, numbers 1 and 2 have CLOSE relationships in meaning and numbers 3 and 4 have OPPOSITE relationships in meaning.
I hope this helps you.
