Question

read this excerpt. which things could earhart and noonan refer to in order to navigate their flight? (please choose two answers.) a satellite tracking technology b radio transmissions c the moon and stars d the sun and stars e bird flight patterns full of optimism, earhart and noonan set off on the longest leg of their journey at 12:30 p.m. on july 2, 1937. they would cross the international date line, so the date they took off from lae and the date they arrived at howland island would be the same. the electra plane was equipped with more than enough fuel, plus the u.s. navy ship uss ontario was waiting midway between new guinea and howland island to receive messages and act as a navigation beacon. in these days before satellite tracking technology, noonan would be plotting their flight using the sun and stars, and depending on radio contact to assist them.

Explanation:

1. Analyze Option A: The excerpt says "In these days before satellite tracking technology", so satellite tracking wasn't available. Eliminate A.
2. Analyze Option B: The text mentions "depending on radio contact to assist them", and radio transmissions are part of radio contact for navigation. So B is valid.
3. Analyze Option C: The excerpt states Noonan used "the sun and stars", not "the moon and stars". Eliminate C.
4. Analyze Option D: The text says "Noonan would be plotting their flight using the sun and stars", so D is valid.
5. Analyze Option E: There's no mention of bird flight patterns for navigation. Eliminate E.

Answer:

B. radio transmissions
D. the sun and stars
