    Reply: Please note that use of the word "perfectly" means that the perfectly elastic alternative is an ideal, theoretical extreme that does NOT actually exist in the real world. As such, the hypothetical, fabricated examples provided here are intended only to illustrate.Water is a good example of a good that has inelastic characteristics in that people will pay anything for it (high or low prices with relatively equivalent quantity demanded), so it is not elastic. On the other hand, sugar is very elastic because as the price of sugar increases, there are many substitutions which consumers may switch to. You may also refer to the attached article for more examples.

    3- Reply: the price elasticity tends to be higher for the good whose total expenditure is higher because people has higher pressure to replace them quicker when their price is relatively high.

    4- Reply: the short run price elasticities are usually smaller than the long run one mainly because it might take time to find proper substitution/solution to reduce the demand of those less cost effective item effectively.
