A Correct answer
Explanation

“Breakthrough” must be lacking the necessary or desirable qualifications as is indicated by the word “though” in first part of the sentence. Thus, “unqualified” replaces the first blank. Also, 'ingenuity' gives sense to latter part of the sentence. Hence, (1) is the answer.
