Question

Accepted Answer

The correct option is 2:

The correct option is **Mc Adam**. The road-making process referred to is known as "Macadamisation," named after the Scottish engineer **John Loudon McAdam** (1756–1836). McAdam developed a revolutionary method for constructing durable and all-weather roads in the early 19th century. His technique involved using layers of small, broken stones placed on a solid sub-base and compacted tightly, with the shape and placement of the stones providing the structural integrity and drainage, eliminating the need for expensive and difficult-to-lay large stone pavements. His work was crucial during the British Industrial Revolution and fundamentally changed global road construction practices.

The incorrect option is 1:
Roahds is not a widely recognized figure in the history of road construction or a Scottish engineer famous for inventing a specific process. This option appears to be a distracter without historical basis related to road engineering.

The incorrect option is 3:
Cyrus Field was an American businessman and financier known for laying the first permanent transatlantic telegraph cable in 1866. His work was in telecommunications, not civil engineering or road construction.

The incorrect option is 4:
Graham Bell, or Alexander Graham Bell, was a Scottish-born inventor, scientist, and engineer credited with inventing and patenting the first practical telephone. His primary field of innovation was acoustic science and communication technology, completely unrelated to road-making processes.
