  D. accepted Japan’s surrender
  Now skim the passage below and answer the question.
  The decision to drop the atomic bombs, once the scientists had developed them, was not lightly made. Operating without knowledge of the highly secret scientific breakthrough, allied military staffs planned to invade Japan in November, 1945, with a second major landing in March, 1946. Japanese resistance in the Pacific islands had been so fierce that the Allied planners anticipated more than a million Allied and two million Japanese casualties. President Truman’s hope was that the atomic bombs—through a demonstration of immense power—would shock the Japanese command into accepting the idea of surrender and save lives on both sides.
  根据前面章节所介绍的有关解答主旨题的方法，考生可以很容易发现文章最后一句话是主题句，这就是文章的大意，因此正确答案为B。
