The use of the conjunction “although” indicates that there is a contradiction in means between the first and the second parts in the sentence. If the colonists resented (meaning hated) the new British laws, they must normally be expected tohave protested against it. But because of the use of the conjunction “although” in the sentence, we must underhand that their action was the opposite of protested.The only choices for the first missing word which are the opposite of protested are “tolerated” and “well-fed.” The pair word of “welcomed; observe” is not appropriate for the second mark because it was not British, but the colonists, who wereexpected to observe the new laws, while the role of the British, as the superior power, was to enforce the new laws. If the British did not enforce the new laws too strenuously, the colonists would not have minded tolerating them. So, it is “tolerated; enforce” the answer
