This questions seems to be a question where you are required to mention more than one point. The question has two options of course, I'll tell you my personal answer to the question in broken up points.
I disagree with this statement because I believe that Physical Education (PE) is a very important subject for each individual.
It has been proven that any sort of physical education improves the activity of your brain, if an individual's level of brain activity is higher, it means he learns more from other education and performs better on his tests.
Physical Education is also a practical lesson that relieves stress off students from all the other core subjects that do not that involve as much practical activity.
Physical Education makes you healthier, the healthier you are the better your life style and (technically) life time will be.
Physical Education is also now proven to wake up students, this means students are less lazy and goes back to one of my previous points mentioning a students activity and performance in a lesson or a test.
I hope this helped, any other questions let me know. :3
Protective systems are methods of protecting workers from cave-ins of material that can fall or roll into an excavation, or from the collapse of nearby structures. As mentioned in earlier chapters, if an excavation is less than 5 feet deep, OSHA does not require a protective systems unless the competent person sees signs of a potential cave-in. (It is important to remember that a wall collapse in a trench four and 1/2 feet deep can still have serious results!) For trenches between 5 feet and 20 feet deep, shoring and sheeting, shielding, sloping and benching are all acceptable protective measures. It is up to the planners of the construction project and the competent person on site to determine which systems will work best. If an excavation is greater than 20 feet deep, a registered professional engineer must design the protective system.
Shoring systems are structures of timber, mechanical, or hydraulic systems that support the sides of an excavation and which are designed to prevent cave-ins.Sheeting is a type of shoring system that keeps the earth in position. It can be driven into the ground or work in conjunction with a shoring system. Driven sheeting is most frequently used for excavations open for long periods of time. Another type of sheeting, in which plates or shoring grade plywood (sometimes called Finland form) is used in conjunction with strutted systems such as hydraulic or timber shoring. These strutted systems are also referred to as active systems. The most frequently used strutted system involves aluminum hydraulic shoreswhich are lightweight, re-usable and installed and removed completely from above

Answer:
Humans were nomads. Their wandering was mainly in search of food and shelter. When they found that certain places had an abundance of food – plant food or animals for hunting, they stayed on. They observed the plants, their growth and when these food sources diminished, they grew plants themselves, from the seeds they collected. This is how agriculture came about.
When humans stopped their nomadic ways and stayed together, it paved the way for formation of the human social structure. Hierarchies were established in due course.
