Mary will drive across town to take advantage of a 40 per cent off sale on a €40 blouse but will not do so to take advantage of a 10 per cent off sale on a €1,000 stereo. Assuming that her alternative is to pay list price for both products at the department store next to her home, is her behaviour rational?.

The whale was a missile blasting from beneath the surface.  2.) a majestic whale leapt skyward before diving back into the sea.    these are both figurative language. this is so because the whale in sentence "1" was not actually a missile, nor was it actually blasting. now, for sentence "2", a whale can not actually "leap".

Thank you so much for asking this question
