Explain me what has happened in this country during the last 10 years.
I would first remark that there are a lot of different avenues in which one can find change over the last ten years. Music, art, pop culture, domestic politics, international affairs, business, technology, demography, medicine, etc, and then tackle each (or a select few) in turn. While doing so, explain the situation as it was 10 years ago, how it is now, and highlight several key transition points in the intervening years. Bonus points if you can find a major category in which there was no remarkable level of change, using specific examples or data points to make the case that 10 years has made little difference.
i would guess that they are testing for reactions by asking this question, judging whether you would try to attempt to answer directly as dave did, try to BS your way through it, or make reactionary remarks based on broad generalizations. i would focus instead on the tools that might be useful in answering such a question, as well as probing for more information about the desired area of focus, etc.
The amount of data gained throught previous history began to double each year.
There are three cans of candies; one with mint candies, another with lemon candies and a third with both lemon and mint candies. The cans are tagged with the type of candy there is inside but you know the tags are not placed on the correct cans. So the question is to find out which types of candies are inside each can with the minimum amount of attempts.
