I checked the sentences myself.There were spelling mistakes to correct.

Question

I need to prepare this listening activity taken from a course book (again). I just want to be sure that everything is OK.

1) Travel and expeditions were much in the people’s mind. Perhaps the most typical figure of the Elizabethan age was the navigator.
2) He was a sea-adventurer or pirate who attacked foreign merchant ships and also dealt in the slave trade; or he was the commander of a ship flying the English flag.
3) Sometimes the two figures merged, as in Sir Francis Drake. The queen officially gave her protection to Francis Drake only as an explorer and tradesman.
4) Drake’s naval exploits, however, with his attacks on Spanish ships were more of a military than a commercial kind.
5) Drake’s circumnavigation of the globe in 1577-80, with his raids on Spanish territories, marked the first stage of a growing patriotism that was to become stronger and stronger.

Answer 1

1, 2, and 5 look fine.

I'd make slight changes in these:
3) Sometimes the two figures merged, as in Sir Francis Drake. The queen officially gave her protection to Francis Drake, but only as an explorer and tradesman.

4) Drake’s naval exploits, however, including his attacks on Spanish ships, were more military than commercial.
