Draw indifference curves that describe a consumer's preference over:

(a.) 1 litre bottled water and 500ml bottled water, when all she cares about is the amount of water she consumes. (10 points)

(b.) left and right gloves with identical colour, size and design. (10 points)

Propose utility functions that represents each of the preferences. What are the axioms that these preferences violate? Justify your answer.
