Answer:
Option 2: Variable names can not begin with a number.
Explanation:
As given Mark and John named a variable as 24_hour_mart while writing a program in python.
While it is forbidden to name a variable starting with any digit, only alphabets (capital and smaller) and underscore can be the first letter of the variable name.
Moreover, by considering the other options given:
- Variable name can include the underscore (_) between the words. It is used instead of spaces that are not allowed.
- There is no upper limit for variable length, it can be of any reasonable length and more than 10 characters say 11 or 12 are reasonable.
- There is no lower limit for variable length, it can be any reasonable length , even it can be of 1 character.
Variables named in python language must not be the keywords as they are reserved for other purposes.

Answer / Explanation:
Coordination numbers, grain growth in ice, and till deformation.
The Web of Science lists 5 papers that Dr. Alley helped write and that have 1986 publication dates. Dr. Alley was studying why some parts of the Antarctic ice sheet move rapidly, and helped learn that deformation of a special type of mud beneath, called till, was involved. He also was studying the physical properties of ice cores, including why and how some crystals or grains in the ice get bigger over time. Some of the physical properties of the ice cores are related to how many different grains are touching each other, which is the coordination number.
Later, Dr. Alley used his knowledge of physical properties in ice to learn how old ice cores are, and to help learn about climate history from them. The other possibilities listed are all things that he studied, some rather closely related, but that were not published in 1986.
Answer:
The statement and the expression is "credits = credits<0?0 : credits;" for the above question.
Explanation:
- The conditional expression is an expression that is used to determine the true and the false case. It works like the if and the else statement.
- It has three parts which are shown above, in which the first part is to check the condition, the second part is excuted if the condition is true and the third part is executed if the condition is false. The variable is used to assign the value.
- If any user provides the credit value and writes the above statement then the credit variable holds 0 for negative value and it holds the original value for any positive or zero value.
