Answer:
It can only be used in superclasses
Explanation:
In computer language, a reserved word is a word that cannot be used as an identifier, such as the name of a variable, function, or label, it is "reserved from use".
If your method overrides one of its superclass's methods, you can invoke the overridden method through the use of the keyword super, it can also be used to refer to a hidden field.
We can conclude that the correct answer is "It can only be used in superclasses" because, in a subclass’ constructor, we can call the superclass’ constructor with the keyword super instead of the superclass’ (constructor’s) name.
I hope you find this information useful and interesting! Good luck!

Explanation:
The following code is written in Python and creates a tuple of 5 integer numbers and then prints out the tuple. Tuples are immutable objects meaning that they cannot be changed at all. Therefore, they have no append methods and cannot have any values added or removed so the last two tasks of this question are impossible to accomplish.
my_tuple = (2, 5, 7, 9, 6)
print(my_tuple)

Internal validity is a method to determine if research has been performed properly. It is based on the number of confounding variables present in the experiment. If an experiment is carried out and confounding variables are avoided, the internal validity is high, and viceversa. In an ideal context, the experiment's internal validity will be high, which will mean its results will be trustworthy.
The students, by making use of a computer software, lowered the validity of the test performed by the teacher.
