Problem four, Kangaroo Day takes place every year on the third Thursday of March. Which date is the earliest possible day for Kangaroo Day?  Is it March 14th, 15th, 20th, 21st, or 22nd? So we need to find the earliest possible date for the third Thursday of March, but we know  that the third Thursday is always exactly two weeks after the first Thursday of March. And so this means that the third Thursday is going to be earliest whenever the first  Thursday of March is earliest. The first Thursday of March can be any day in March, so the earliest date is when it's just on March 1st.  Then two weeks after that is 14 days after that, which is March 15th, and so the answer is B.

Video Summary

The earliest possible date for Kangaroo Day, held on the third Thursday of March, is March 15th. This is because the third Thursday occurs two weeks after the first Thursday, which can be as early as March 1st. Thus, two weeks from March 1st is March 15th, making it the earliest possible date for Kangaroo Day. The answer is B, March 15th.
