If 50 out of 100 sites inspected have mosquito larvae, what is the simple breeding index?

Explanation:
The simple breeding index is the proportion of inspected sites that have mosquito larvae. Here, 50 of 100 sites are positive, so 50/100 = 0.5. Expressed as a percentage, that’s 50%. Since the question presents 50% as an option and field reports typically use percent, this is the best match. The other options would represent different proportions (0.25 = 25%, 0.5 decimal would be 50% but the provided percent form is the standard presentation), which don’t reflect the observed data.
