ANS:D - Neither I nor II is implicit

Explanation: It is mentioned that entry only through main routes has been banned. So, I is not implicit. Besides, the entry has been banned to reduce the volume of traffic on roads and ease congestion. It could only be done at the entrances to the city and not within the city itself. So, congestion by the city vehicles is unavoidable. Hence, II is also not implicit.

ANS:C - LSI

LSI = Large Scale Integration.

ANS:B - compression

The size reduction mechanism predominantly used in Jaw crushers is compression. Here's why:

1. Compression:
   • Jaw crushers operate by compressing rock between two surfaces, one of which opens and closes like a jaw (referred to as a swing jaw).
   • The material is crushed by the compression forces generated by the movable jaw against the fixed jaw.
2. Other Mechanisms:
   • Impact: While there may be some impact involved when the material is initially fed into the crushing chamber, the primary mechanism once crushing begins is compression.
   • Cutting: Cutting action is not typically a significant mechanism in jaw crushers.
   • Attrition: Attrition involves rubbing and friction between particles, which is not the primary mode of size reduction in jaw crushers.
