Answer:
The answer to this question is given below in the explanation section.
Explanation:
The value stored by a variable can be changed after it is assigned(true).
The value of a variable can be changed after it is assigned, for example:
int a=10;
and we can change the value of variable a in letter program such as:
a=15;
Variables are a name for a spot in the computer's memory (true).
it is true, because the variables value stored in the computer's memory and we can access theses values by their name (variable name). so Variables are a name for a spot in the computer's memory.
Variable names can be words: such as temperature or height (true).
Yes, the variable name can be words such as height, width, temperature etc.
The value stored by a variable cannot be changed after it is assigned (false).
It is noted that the value stored by a variable can be changed after it is assigned. However, it is noted that is some programming language, you can't change the value of static variable.
W. E. B. DuBois's "The Souls of Black Folk" is an important work that continues to resonate today. In it, DuBois argues that the black experience in America is fundamentally different from that of whites, and that this difference is the result of racism. He further argues that the black community must develop its own institutions and culture in order to thrive.
DuBois's arguments are as relevant today as they were when he wrote them. The contemporary prison system is a clear example of how racism continues to impact the lives of black Americans. Black people are disproportionately incarcerated, and the conditions in many prisons are abysmal. The lack of access to education and opportunities for rehabilitation means that many black Americans are effectively condemned to a life of poverty and despair.
DuBois's work is a call to action for black Americans to create their own institutions and to fight for their rights. The contemporary prison system is a clear example of how much work still needs to be done.

Answer:
c. This would reduce the number of tuples to involve in the join resulting in a more efficient query.
Explanation:
SQL or structured query language is a database querying language used to communicate or interact with databases. A database query could be as simple as returning all the columns from a database table to complex like joining several query results which in turn forms an algebra expression.
Every query statement or expression is executed with time, execution time needs to be minimized for efficiency, so, a well-arranged and reduced joining in the query improves the efficiency of the query.
