Q: Step forward with your left leg if you’re leading, or step backward with your right leg if you’re following. Both you and your partner should step at the same time. Keep your step quick because it’s a single beat. During the dance, maintain a stance that is comfortable for walking. The movement of the two step is similar to walking. Move your right leg forward if you’re leading or your left leg back if you’re following. Make the step quickly and together, counting out 1 beat. Don’t worry about bringing your feet together because it isn't necessary. Slow down your movement so that this step takes 2 beats instead of 1. Step forward with your left leg if you’re the lead or step backward with your right leg if you’re following. Once again, both partners should step together. You’ll step the same way as you did for the first step, but this time it will be slow. If you’re the lead, move your right leg forward. If you’re following, step backward with your left leg. Go slowly so that your step takes 2 beats. Step the same way as you did in the second step but go slowly. The line of dance is an imaginary line that goes around the dance floor. Faster dancers stay to the outside of the dance floor, while slower dancers move closer to the inside. Stay in the line that best matches your pace so that you don’t accidentally bump into other dancers.  This line will move counter-clockwise. If people are line dancing, they'll do it at the center of the dance floor inside the line of dance.
A: Count 1 beat for the first quick step. Take a quick second step to the 2nd beat. Step slowly on beats 3 and 4. Take another slow step on beats 5 and 6. Follow the line of dance if you’re dancing alongside other couples.

Article: Because lightning strikes can cause cardiac arrest, aggressive resuscitation may be necessary. If you cannot dial 9-1-1, designate someone else to. Do not put yourself in danger trying to help a lightning strike victim. Either wait until the immediate danger has passed, or move the victim to a safer location. Despite the common myth, lightning can strike the same place twice. People struck by lightning do not retain an electrical charge, so you can immediately touch them and begin treatment.  Do not remove the burned clothes unless absolutely necessary.   Perform Child CPR if the victim is a child.  Perform Adult CPR on adult victims. Lay the victim down on his or her back with the head resting slightly lower than the torso. Elevate and support the legs.
Question: What is a summary of what this article is about?
Call emergency services. Make sure it is safe to help. Start CPR. Treat the victim for shock.

Q: Newton's second law of motion states that force equals mass times acceleration: F = ma. If you know the net force on the object, and it's acceleration, you can rearrange this formula to find the mass: m = F / a. Force is measured in N (newton), which you can also write as (kg * m)/ s2. Acceleration is measured in m/s2. When you calculate F / a, the units cancel to give you an answer in kilograms (kg). Mass is the amount of matter in an object; this does not change unless you cut off part of the object, or attach more material. Weight is a measurement of gravity's effect on mass. If you move the object to an area with different gravity (such as from the earth to the moon), it's weight will change, but it's mass will not. An object with more mass does weigh more than an object with less mass, if they're experiencing the same gravity. . If you're doing your chemistry homework, you may come across the term "molar mass." This is a related concept, but instead of measuring an object, you measure exactly one mole of a substance. Here's how to calculate it in most contexts:  For an element: look up the atomic mass of the element or compound you are measuring. This will be in "atomic mass units" (amu). Multiply by the molar mass constant, 1 g/mol, to put it into standard molar mass units: g/mol. For a compound: add the atomic masses of each atom in the compound to find the total amu of the molecule. Multiply this total by 1 g/mol.
