With regard to quantified statements, is it possible to say that the opposite of â€˜true for allâ€™ is â€˜false for at least oneâ€™? Illustrate your reasoning with some examples.

Yes that is correct.

All mammals give birth to live young. = True for all. And to give the opposite would be "At least 1 does not birth live young".
