48. Animal which captures and readily kills living animals for its food is called:

49. In a railway track, two rails are joined end to end with a gap tin between them because:
A. Steel can be saved
B. Accidents due to contraction in winter can be avoided
C. Air gaps are necessary for bearing the weight of running train
D. Accidents due to expansion in summer can be avoided
e. All of these
differences in temperature cause the materials to either shrink or expanD. With a lot of shrinking and expanding occurring, these materials would crack or break down if there wasn’t any allowance for the movement. Also these gaps are used to compensate for the weight of the load crossing vehicles which presses the bridge to its maximum shear capacity. The gaps serve as this allowance for movement in terms of both temperature and weight.
