Read the passage and answer the questions. Many people believe that multitasking makes them more productive. Research suggests otherwise. When we switch between tasks, the brain needs time to refocus, and these small delays add up. Studies have found that people who frequently multitask make more errors and take longer to finish work than those who focus on one task at a time. Switching also increases stress, because the mind never fully settles. Experts recommend grouping similar tasks together, turning off unnecessary notifications and setting aside blocks of time for deep work.
