Answer: i think the age that the author says its probably talking about like maybe primary school because it talks about how "its more important than they were in primary school" and i feel like there talking about when you start college and the new study's and skills were more important so maybe the answer would be that teachers give work assignments to students to give them new information and also teachers give homework to students because they want there students to learn new stuff and focus on what really matters like for the future and college. and also for my answer for the age it would probably would have to be "younger kids" and for older students" to i hope this helps.
Explanation:
courtesy, courtesy is the showing of politeness in attitude and behavior towards a person
here are ur two suggestions
1.)One of the main causes of acid rain is a sudden drop in the pH levels of water and that happens because of absorption of harmful gases by the atmosphere. The best way to restore the pH balance of water is to limit the use of items which run on gasoline. Instead use products which run on electricity; as they are much easier to run and maintain.
2.)Another great thing that all people can do is to learn how to drive cars efficiently. While driving on roads there are a lot of things that can be done to reduce smoke emission from cars. Drivers should ease up as soon as the yellow light rather than slamming on the brakes and they shouldn't rush away as soon as the lights turn green. These small practices help reduce the wastage of gasoline and helps people save a lot of money on fuel.
i hope this helps!!! have a great day!!!
