Final answer:
The question seems to inquire about the reproductive rates of a species after a period of resource deprivation, the 'average brood size' being a measure of offspring production post resource reintroduction. The specific number sought cannot be provided without detailed experimental data. The reference to favorable conditions implies an expected increase in reproduction.
Step-by-step explanation:
The student's question appears to be related to a study or experimental situation involving the reintroduction of food to a population of organisms, possibly insects like flies or mosquitoes, following a period of absence or limitation of resources, here referred to as 'ard'. The 'ard' might be a typo and may stand for a period of resource deprivation. The 'average brood size per mated individual' would refer to the number of offspring produced upon the reintroduction of food after this 30-day period.
The question seems to be looking for the number closest to the average brood size produced by these reintroduced individuals—information that might be available in experimental results or a data chart provided in the context of the question. Without the specific data from the study, it is not possible to provide the exact number for the average brood size. However, one can assume that the reproductive rates would potentially increase, based on the provided information indicating favourable conditions for offspring production in part 'c' with temperatures above 30°C and humidity below 60%. This is similar to favourable conditions mentioned in studies on species like mosquitoes, which are known to increase reproductive rates under optimal environmental conditions.
