First of all, it is not really a tough question ;-)
What you have there is a SYN packet (which is used in the TCP handshake session setup), and in that packet optional TCP parameters are given - see RFC 1323 for more details on what and why.
All of these are so called high performance options that are now pretty common since all modern TCP stacks know about those and use them, especially in high latency high bandwidth environments (LFN).
