In relation to the circuit presented below, mark the alternative(s) that you consider correct. 1 To enable actuator A2 to advance, it is necessary to switch valve V2 to the leftmost position and ensure that valve V1 is in its initial (intermediate) position. 2 Switching valve V2 to the leftmost position allows actuator A2 to advance, but for this to happen, valve V1 must also be switched to the leftmost position. 3 When activating valve V1, using the locking lever installed on the left side of it, the two actuators (A1 and A2) are allowed to advance. 4 Hydraulic pump B1 is a simple variable displacement type. 5 Valves V1 and V2 have a TANDEM center.
