Q1. Identify the statement which focuses on the newest possible cause of an asthmatic attack:
Explanation
The stem asks for the newest possible cause, so the time signal in each statement matters. A diet deficient in antioxidants is presented as a newer suspected explanation for asthmatic attacks. Atmospheric pollution is said to worsen the condition, not to introduce the latest cause. Household dust mites are described as something that was already thought to trigger attacks, showing an older understanding. Dietary allergies are only suggested as a possible major factor, but not as the newest line of explanation. Therefore the antioxidant-deficient diet best matches the question.
