Environment minister: Many countries have signed an international agreement that is intended to reduce pollution in the world' s oceans. While conformity to this agreement probably would significantly reduce pollution in the world' s oceans, it would also probably reduce economic growth in our country and others. Ttherefore, our country should not sign the agreement. Which one of the following principles, if valid, would most help to justify the environment minister's argument? ['A country should not sign an agreement that is unlikely to achieve its stated goal.', 'If a policy is likely to protect the environment and is unlikely to reduce economic growth, then governments should implement that policy.', "When deciding whether to sign an agreement, a country should consider the agreement's effects on other countries' economies as well as on its own economy.", "It is more important to maintain economic growth in one's own country than it is to reduce pollution in the world's oceans."]
