Statement 1 is automatically true, so it really only tells us that it is possible to divide the number of baskets by 2. But we might have 2 baskets with 10 oranges each, or 20 baskets with 1 orange each, for example, so that information is not sufficient.
If Statement 2 is true, then when we double the number of baskets, we must get a number greater than 20. Since the number of baskets also needs to be a divisor of 20 (for it to be possible to distribute 20 oranges evenly among the baskets) the only possibility is that we have exactly 20 baskets, with one orange in each.
