The graph below shows the movement of an object at several points in time. Using the formula Average Speed = Distance / Time, what is the average speed of the object? 0.5 meters/minute 0.5 meters/minute 25 meters/minute 25 meters/minute 2 meters/minute 2 meters/minute 50 meters/minute

answer; the basal forebrain;

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
