The passage mainly explains

how habits form through a cue, routine, and reward loop (The passage centers on the three-part habit loop and how it operates.)

Why does the passage suggest keeping the cue and reward while changing the routine?

Because the loop still triggers and pays off, but with a better action between (The text says the trigger still fires and the payoff still arrives, but the routine in between is replaced.)

According to the passage, what does the reward do?

It signals to the brain that the loop is worth remembering (The text states the reward is 'the payoff that tells the brain the loop is worth remembering.')

In this passage, "deliberating" most nearly means:

thinking a choice over carefully (The text says the brain "stops deliberating" once a loop is learned, meaning it stops thinking the choice over and lets the cue pull the routine along automatically.)

The Loop Behind a Habit: Level 3 Reading Comprehension Questions

A habit is a behavior the brain has learned to run on autopilot. It usually forms around a simple loop with three parts: a cue, a routine, and a reward. The cue is a trigger, such as a time of day or a feeling. The routine is the action itself. The reward is the payoff that tells the brain the loop is worth remembering.

When the same loop repeats often enough, the brain stops deliberating and lets the cue pull the routine along almost automatically. This saves effort, which is the whole point: habits free attention for harder tasks. But the same machinery that builds helpful habits also builds harmful ones, because the brain does not judge whether a reward is good for you, only whether it feels rewarding.

This is why willpower alone rarely changes a habit. A more effective approach keeps the cue and the reward but swaps the routine in between for a better one. The trigger still fires, the payoff still arrives, but the action that connects them is replaced.
