Show answer and explanation

Correct answer: (A) The neutral point shifts towards the roll entrance.; (B) The rolling load is decreased.

Explanation

Front tension helps draw the strip through the roll gap, reducing the compressive rolling load. It shifts the point where strip and roll speeds match toward the entrance, enlarging the forward-slip region. Thus **A,B**; the exitward shift and increased-load statements are false.
