A.I. Explanation:

Option 1: "Employers act illegally by not giving breaks."

Explanation: The text states that lunch breaks are obligatory by law, but it does not claim that employers are acting illegally. Instead, it focuses on the behavior of workers who choose to skip breaks, not on employers' actions.

Option 2: "Working through the break increases the amount of work completed."

Explanation: The text argues that working through lunch actually reduces productivity, contradicting this option. It highlights that taking breaks is necessary for concentration and combating stress.

Option 3: "Less work gets done during the lunch hour."

Explanation: This option misinterprets the text. The author does not state that less work is done during the lunch hour; rather, it emphasizes that skipping breaks leads to reduced overall productivity.

Option 4: "Too many workers misuse their allotted breaks."

Explanation: This option accurately reflects the author's point that many workers do not take their full lunch breaks or skip them altogether, which is described as a misuse of their allotted breaks. The text supports this by providing statistics on workers' behaviors regarding lunch breaks.
