Ten years ago or more, I remember it snowing around the beginning of November. Now its mid-December and the weather has gotten very cold, then cold and even up to mild, and the repeated again. Snow for the past few years hasn't come until January, and I'm just wondering why. By the way I live very close to Detroit, Michigan, and Windsor, Ontario, Canada.

for someone who teaches EKG. What is the answer for the following question.
" Which of the following electrocardiograph leads records electrical activity from the midpoint between the left arm and left leg to the right arm?"
Is the answer lead III or aVR? My teacher said it's lead III. But my textbook said it's aVR lead. My teacher mark it wrong on the test and wouldn't give me the point back. I'm really upset. Why is the information in textbook different than what is on the test?
