When evaluating Thornton's Rule, which states that energy expenditure is proportional to oxygen consumption, the key idea is that energy can be estimated from the amount of O2 used across various activities over a given period.
Option 1: 'We can measure energy used in all the listed activities' correctly reflects the central implication of the rule, because if O2 consumption is measured, energy expenditure can be inferred for any activity, not just a specific task. This encompasses rest, sleep, and all kinds of physical activities since each uses some amount of O2.
Option 2: 'Bowling' concerns a specific activity that uses oxygen, so by itself it indeed would allow energy estimation via Thornton's relation, but describing it as the sole or representative activity ignores the general applicability to other activities and thus is incomplete.
Option 3: 'Sleeping' involves metabolic energy use and O2 consumption, but treating it as a separate example would imply energy can be measured in isolation for one state without acknowledging the broader range of activities; Thornton's rule applies across different states of activity, including sleep, but the option as a standalone claim is too narrow.
Option 4: 'Bicycle riding' is a type of physical activity that consumes O2 and thus energy can be estimated from O2, but like the bowling example, selecting a single activity does not capture the general principle; the rule applies across diverse activities, not exclusively to cycling.
Option 5: 'Running' also fits the rule, as running increases O2 consumption and energy expenditure, yet choosing it alone would misrepresent the universal applicability of the rule to other activities beyond running.
In summary, the most comprehensive interpretation is that energy expenditure can be measured across all listed activities because Thornton's Rule links energy use to oxygen consumption in any activity, whereas selecting any single activity as representative would misstate the rule’s broad applicability.
