Write a single SQL statement for each of the following queries.

Questions: 1. What are the team ID and the meeting frequency for the Cyclone team? 2. Which countries have agents with Presidential or Majestic clearance? (Your query shouldnt depend on what clearance IDs are used for these clearance levels, just the names of the levels.) 3. What are the ids and last names of all agents with at least two skills? (You can do this without COUNT.) 4. List the name and status of all missions that have at least one agent who speaks Russian. Dont repeat missions in your result. 5. Which pairs of agents have the same first and last names? (List each pair only once.)
