Question

Because experiments involve careful manipulation of all factors of interest and careful control of all others, which experiment would not be ethically allowable? the effect of classical music on the ability to solve crossword puzzles the effect of room lighting on color preference the effect of supplementary vitamins on retirement age the effect of prolonged solitary confinement of toddlers on language development

Answer 1

Based on the choices, I believe the experiment that would not be ethically allowed is the effect of prolonged solitary confinement of toddlers on language development. This is because this might negatively affect the language and also mental growth of the toddlers. Toddlers are very fragile and sensitive hence any confinement will affect their growth. It is also against their rights.
