Geologists believe that the warning signs for a major earthquake may include sudden fluctuations in local seismic activity, tilting and other deformations of the Earth's crusts, changing the measured strain across a fault zone, and varying the electrical properties of underground rocks.
A) changing the measured strain across a fault zone, and varying
B) changing measurements of the strain across a fault zone, and varying
C) changing the strain as measured across a fault zone, and variations of
D) changes in the measured strain across a fault zone, and variations in
E) changes in measurements of the strain across a fault zone, and variations among
answer is D.
Question:
1)划线部份应与谁平行?
2)tilting and other deformations of the Earth's crusts 在句中作何成分? 难道这里就平行吗?
