What role did Sir Francis Drake serve after claiming land in North America?

Sir Francis Drake is best known for his accomplishments as an explorer and privateer in the late 16th century, particularly for his circumnavigation of the globe and his role in the defeat of the Spanish Armada. After claiming land in North America, particularly in the region he named Nova Albion (now California), Drake was indeed involved in political life, serving as a Member of Parliament. His experiences and status also led him to play a significant role in colonial affairs, which included aspects of governance related to England's burgeoning overseas territories.

His dual involvement in both parliamentary functions and colonial governance is what makes the answer correct. Drake's prominence and contributions allowed him to influence the English colonial agenda and participate actively in legislative discussions. Thus, his roles collectively characterize him as both a member of parliament and in governance related to English colonies, justifying the designation of "both."
