Answer:
Option B = a conflict between an individual role and group goals.
Explanation:
In the question above we can see that one out of the group members( Bert) make fun of almost everything and at first the other members in the group look at Bert as a someone that is so funny but later they are do not love his CONSTANT jokes and unseriousness anymore.
The reason the other group members became unhappy with Bert is because Bert is not abiding with the group goals. Bert role in the group was never to be unserious but that is what he is doing so there will surely be a Conflict between Bert roles in the group and the group goals. Work is work, there is no harm in little fun though, but work is always work that is the reason they brought the group together in the first place.
Answer: D) To freely trade with the bloc's other member countries.
Explanation:
Free trade means there aren't any tariffs between any two countries. So any two countries can sell whatever goods they want without any extra taxes, fees, etc added on.
Choices A through C all describe situations in which trade is reduced/restricted between any two countries. This makes a nation more independent, but the drawback is that they aren't connected to the global stage as much.
Theoretically in an economic sense, a country is better off being connected more globally because it allows for specialization to happen and it lowers costs. Of course on a practical realistic level, things are more complicated but this is the general idea at least.
