Keith Nolan was moving through the ROTC training successfully until it came time to pass to the third ROTC level. What was the specific part of moving from the second to the third level that stood in his way?

The role must be governor general

Maybe c. im not too positive

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
