224. (a) overcome deficiencies in current geologic hypotheses (Becasue the first para suggests about this "apparently improbable concept" and tells that "evidence from physicists compelled geologists to reinterpret their data")
225. (c) there should be cooperation between different fields of science (Because the last line suggest that "If, however, physicists could show that the Earth’s gravitational force has decreased with time, expansion would have to be reconsidered and accommodated" i.e, views of both physicists and geologists should be taken into account)
226. (d) making unwarranted comparisons (Because the second para tells that "The cases are not precisely analogous")
227. (d) proportional to the size of the Earth (Because the last line tells that "Earth’s gravitational force has decreased with time, expansion would have to be reconsidered and accommodated". So if gravitational force has decreased then the the earth is expanding i.e, gravitational force is related to size of the earth.)
