Spring is here and I am ready to cut loose.

1.What is that, which always keeps growing but is never less?

That's my staked VYB.

2.Which is such a fruit that is sweet when it is raw but sour when ripe?

That really depends on your preference. @buffalobison likes it raw and that's sweet, but some actually prefer a ripe cherry. @beeber just likes everything sweet.

3. If 5 Rabbits Eat 5 Carrot in 5 Minutes then How many Carrots will 10 Rabbits Eat in 10 Minutes?

There are a lot of assumptions here, but let's assume there is an unlimited supply of carrots all the same size and all the rabbits eat at the same rate regardless of how many carrots are consumed. Then the answer would be 20 carrots, but given the sugar content in a carrot I think after five the rabbits would become so hyper that they would forget about eating carrots and get on to some other activity.
