First, multiple-choice questions (this question marks out of 84 points) Note: This question a total of 14 small questions. Each question has five answers (A), (B), (C), (D), and (E), of which one and only one answer is correct. Please write the code in front of the answer that you think is correct in the parentheses after the question. The correct answerer gets 6 points, the wrong answer score gets 0 points, and the unanswered person scores 1 point. 1. There are five consecutive integers (arranged in ascending order). The sum of the squares of the first three integers is equal to the sum of the squares of the last two integers. Then all five consecutive integers share (A) 1 group: (B) 2 groups; (C) 4 groups; (D) 0 groups (absent); (E) infinite groups ()
