They are linked because they are mentioned and both have pages.  Also it does not make sense for a line about exploration or explosives to be linked to bounty hunting.  Notice the word exploration is linked to exploration and explosives is linked to explosives.  If there was a mention of bounty hunting then it would be logical to have the word bounty hunting linked to bounty hunting.
