Construction work is being carried out for a railway route passing close to a mountain slope. why is it necessary to cover the mountain slope with a wire mesh?
a. wire mesh transmits electrical pulses to soften the rock.
b. wire mesh protects vegetation on the slope from emissions.
c. wire mesh prevents rocks from sliding down the slope and onto the train track.
d. wire mesh absorbs surface runoff water, especially during heavy precipitation.
e. wire mesh absorbs shockwaves from the ground during mild seismic events

Option C, Wire mesh prevents rocks from sliding down the slope and onto the train track

Explanation:

Wire mesh is used as a barrier to the rock fall. Usually while working in mountainous or hilly regions,  use of heavy equipment’s and machine in construction activities produces seismic vibrations which can easily destabilize the rock slides in the mountainous regions. The detestable rocks tend to move downward. In order to prevent these rocks or rock slides from falling on to the clear site of highway/railway and also to keep the working man force safe from any sort of causality wire mesh are used to restrict the falling debris and rocks.

answer; the correct answer is (beta)

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this
