Answer:
Blogging
Explanation:
This is confusing. I think it would be B because most people who blog have their own website which is not a social networking site.
Answer:
The answer is "healthful".
Explanation:
- In ancient times the vast majority of people lacked food, parents aimed at providing their family members with adequate food. Recent months, interestingly, also made parents should be aware of providing a healthy diet for their children, including links to being enough and a wide taste of options.
- In societies of food scarcity, it could see that the main concern of families continues and provide subsistence families with sufficient food. It is careful to prevent a common "good food".
This is called a key attribute!
There are different types of key attributes!
Primary key is the key that is actually chosen, for example a social security number.
There is also a unique key, say our finger prints! they also uniquely identify humans, but usually we prefer to use social security number when we list people (a unique key could be a primary key if we chose so)
We could also identify people by their social security number and a name, but this is unnecessary, as social security number already gives a full identification. Such a reduntant key is called super key.
