Answer 1

After the changes in both price of a normal good and income the consumer will buy the same amount of this good either both price and income increased or they decreased, because the proportion of his consumption will not change.
But after the changes in both price of a superior good and income the consumer will buy more of this good, if the price and income increased and less of this good, if the price and income decreased, as for superior goods there is both income and substitution effects.
