    Select Question Language :


    For many years, skeptics scoffed at the idea that plants respond to environmental stimuli other than those that directly affect the process of photosynthesis. Recent studies, however, offer contradictory evidence that seems to suggest that music, for instance, can have a direct and positive effect on plant development. Plants that were kept in the presence of music during the first six weeks of development grew considerably faster and showed fewer signs of disease than those plants developed in silence. The “music-advantaged” plants were also 35 percent more likely to survive the process of transplantation initially than were the “music-disadvantaged” plants.

    Which one of the following is an assumption upon which the above argument is based?

    Options :-

    1. Many skeptics still do not believe that music is beneficial to plant development.
    2. Plants that do not thrive have been deprived of music during the first six weeks of their development.
    3. Plants that were exposed to music for longer periods of time were healthier and grew faster than those with less exposure.
    4. Music does not significantly damage a plant's ability to photosynthesize.
