Answer:
The bicycle is a tremendously efficient means of transportation. In fact cycling is more efficient than any other method of travel--including walking! The one billion bicycles in the world are a testament to its effectiveness
Explanation:
The elements of a good study environment are that it must be well lit the resources are near it is quite and it is clutter free
Explanation:
A good study environment must be an environment that will promote the good study conditions and it must be quite and calm if a person studies in that environment all the resources like the food water and the other refreshments must be available in that environment
The environment must be clean and it must be clutter free without any disturbances and hence these are the factors that will promote the good study environment
The answer is a.two

Answer:
The solution code is written in Python 3:
- def modifyList(listNumber):
- posCount = 0
- negCount = 0
-
- for x in listNumber:
- if x > 0:
- posCount += 1
- else:
- negCount += 1
-
- if(posCount == len(listNumber)):
- listNumber.append(max(listNumber))
-
- if(negCount == len(listNumber)):
- listNumber.append(min(listNumber))
-
- print(listNumber)
-
- modifyList([-1,-99,-81])
- modifyList([1,99,8])
- modifyList([-1,99,-81])
Explanation:
The key step to solve this problem is to define two variables, posCount and negCount, to track the number of positive value and negative value from the input list (Line 2 - 3).
To track the posCount and negCount, we can traverse through the for-loop and create if else statement to check if the current number x is bigger than 0 then increment posCount by 1 otherwise increment negCount (Line 5- 9).
If all number in the list are positive, the posCount should be equal to the length of the input list and the same rule is applied to negCount. If one of them happens, the listNumber will append either the maximum number (Line 11 -12) or append the minimum number (Line 14-15).
If both posCount and negCount are not equal to the list length, the block of code Line 11 -15 will be skipped.
At last we can print the listNumber (Line 17).
If we test our function using the three sets of input list, we shall get the following results:
[-1, -99, -81, -99]
[1, 99, 8, 99]
[-1, 99, -81]
I’d say monthly. It probably wouldn’t kill you to do it every three months though.
