Katen [24]

Answer:

C. The motor tasks performed in the experiment were too simple.

On this case is the best option since the student wants to explain the effect of motor imagery and action observation together into the excitability. And maybe is too simple, since we need to cover other possibilities in order to analyze the excitability.

Explanation:

A. The procedure used did not include MEP recordings prior to each task.

Not true, is not a requisite record MEP prior to the task to evaluate the variable of interest on this case.

B. MEP amplitudes in an individual are typically highly consistent.

The Motor evoked potentials (MEP) "are electrical signals recorded from neural tissue or muscle after activation of central motor pathways". But on this case that's a technical aspect related to the topic and this not would be the reason why we need to withhold the presentation

C. The motor tasks performed in the experiment were too simple.

On this case is the best option since the student wants to explain the effect of motor imagery and action observation together into the excitability. And maybe is too simple, since we need to cover other possibilities in order to analyze the excitability.

D. The six different conditions were run in random order.

That's not true the student are not analyzing 6 different conditions, just 2.

Which means for obtaining hydrogen from water would require the most energy??
Flauer [41]
I think the correct answer would be to electrolyze water (run an electric current through it) to decompose it into hydrogen and oxygen. Assuming 100% efficiency, it is said that it needs about 40kWh per kilogram of water to fully decompose it.

How are the different firework shapes produced
AleksAgata [21]

To create the shapes, stars are arranged on a piece of cardboard in the desired configuration. If the stars are placed in a smiley face pattern on the cardboard, for example, they will explode into a smiley face in the sky. In fact, you may see several smiley faces in the sky at one time.
