Answer:
Early in the history of technology, the development of tools and machines was based on technical know-how versus scientific knowledge as is done today.
Explanation:
In the era prior to technological development, men had a basic and at times rudimentary manufacturing development, based on artisan processes that developed their tools and machinery by hand, without any type of automation or mass production rules.
Thus, each part or tool was manufactured in a unique way, which required a broad mastery of the production process by the manufacturer. This is how the first professions began to emerge, such as blacksmiths for example, who mastered the technique of manufacturing different implements and carried them out without any scientific knowledge.

Answer:
c. The pivot could be either 7 or 9.
Explanation:
Since we are trying to sort an array of eight integers using quick sort, from the first partitioning it shows that the pivot or the central point can either be 7 or 9. When you look at the array, it is only 7 and 9 that are placed correctly in the sorted array. Every element to the left of 7 and 9 are smaller and every element on the right of 7 and 9 are integers higher than them. Hence this shows that the pivot lies between 7 or 9.
Answer:
int n = -100;
ii. int m = 2, p=4;
vi. double d = 0.67F;
vii. char c = '$';
Explanation:
A variable can be declared starting with a character,dollar sign or underscore not with an integer.you cannot use the same variable that you are declaring in it's definition.
For strings you have to use double quotes.
For declaring multiple variables you can do that by separating different variables by commas.
int a=4,b=44;
as long as they are of same data type.
In iv part if there is a variable m that is defined before variable x then it is valid.
