Q1. A rectangular paper is folded along a line parallel to its longer side, exactly in the middle. The resulting rectangle is then folded along a line parallel to its shorter side, exactly in the middle. If a single cut is made from the center of the final folded rectangle to the midpoint of one of its longer sides, how many distinct straight-line cuts will be visible on the unfolded paper?

2 4 6 8

Q2. In a system designed to manage train headways (the time interval between successive trains), a rule might detect a potential safety issue if the actual headway between two trains deviates significantly from the minimum safety headway. If the system simultaneously logs anomalous speed readings from the preceding train, what is the most likely cause for the rule violation?

A deliberate increase in speed by the following train. A faulty sensor on the following train. A malfunction in the preceding train's speed control or reporting system. An error in the headway calculation algorithm.

Q3. What figure represents the relationship: 'Parents', 'Mothers', and 'Fathers'?

Three overlapping circles. Two separate circles inside a larger circle. One circle inside another, with a third circle separate. Three separate circles.
