50. The steps in an algorithm to drive a vehicle are given. Which two steps should be switched to make the algorithm successful?
Answer: A
Steps 1 and 4 should be switched to make the algorithm successful.
Switching steps 1 and 4 in the algorithm will create a logical sequence necessary for successfully driving a vehicle. This adjustment ensures that the vehicle is properly prepared before initiating movement.
A) 1 and 4
This option is correct because step 1 likely involves starting the vehicle and step 4 may pertain to checking surroundings or ensuring safety before driving. By switching these steps, the driver will ensure that the vehicle is operational before assessing the environment, leading to a more effective driving process.
B) 1 and 2
Switching steps 1 and 2 would not be effective because both steps are crucial to the initiation of driving. If step 1 pertains to starting the vehicle and step 2 involves another preparatory action, interchanging them would disrupt the necessary order and could create confusion in the driving sequence.
C) 2 and 5
This option is incorrect as it likely involves switching a preparatory step with a concluding action related to driving. The sequence of operations is important; thus, interchanging a step that should logically follow another would not enhance the effectiveness of the algorithm.
D) 1 and 3
Switching steps 1 and 3 is not advisable, as it would likely disrupt the flow of the algorithm. If step 3 involves an action that should occur after the vehicle is started, this change would create a gap in the procedure necessary for safe driving.
Conclusion
The correct adjustment of switching steps 1 and 4 ensures that the vehicle is operational before evaluating the environment, which is vital for safe driving. All other options would either disrupt the logical sequence or fail to enhance the effectiveness of the algorithm, leading to potential safety issues.
