Write an explanation for how to perform some kind of physical activity, such as riding a bike or playing sport

Alright here we go. Haha.

Riding a bike:
1.) Purchase Bicycle.
2.) Approach bicycle by locking ankle joints and back in place. Move knee and hip joints forward and backward in a repeating motion.
3.) Get on bicycle by locking left (or right depending on loaction) leg, hip and ankle joints in place while reaching right leg over bicycle. Keep balance in the center by keeping your back and your head steady.
4.) Once on bicycle, push off with your dominant foot while keeping the other side of your body balanced and your foot on the pedal. Once in motion, maintain balance by being centered and not moving left or right. Get your dominant foot back on the adjacent pedal from your other foot.
5.) Let your goal always be to continually push down on the pedal upwards while also pushing it forward.
6.) If done correctly, the previous steps should get you moving on your bike. Remember to stay balanced and to have fun.

If you need an explanation for stopping or getting off, let me know. :)

Travelers on Highway 66 today can easily experience this past through the many motels, gas stations, cafés, trading posts, and roadbeds that remain along the highway.

It was sold as "the shortest, best, and most scenic route from Chicago through St. Louis to Los Angeles."

Business owners in small and large towns along the highway looked to Route 66 as an opportunity for attracting new customers to their often rural and isolated communities.

Explanation:

The 3 sentences give factual information while the other 2 sentences that you can select talk about how it is popular or how it is an endangered site, not about factual information on Route 66
