Why was Mary Walker a trailblazer?
Please help

the president was the speaker and it was a great part of history.

explanation:

video of the national aeronautic space administration's (nasa) coverage of president john f. kennedy’s address at rice university, houston, texas, concerning the nation's efforts in space exploration. in his speech the president discusses the necessity for the united states to become an international leader in space exploration and famously states, "we choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard."

uncanny would be like unlucky or disaster. you can look for more in the dictionary or if you have text book then turn to a. 17 but it's different with textbooks.

lemme actually be useful and say i believe the answer is the first one.
