Answer:

I. The class methods and instance methods of one class may call the public class methods of another class using dot notation and referencing the name of the other class.

Explanation:

Private methods are being accessed from only within the class or scope specified. No other means of accessibility is possible, and even through inheritance. And instance methods can never call without using dot notation, any of the class method of the same class. Hence second and third options are not correct. And the class method and the instance methods of one class may call the public class methods of another class using the dot notation and referencing the name of the other class. Hence, the correct option is the first one.

Free_Kalibri [48]

In this question, we are given ,

A certain list, L, contains a total of n numbers, not necessarily distinct, that are arranged in increasing order.
L1 is the list consisting of the first n1 numbers in L.
L2 is the list consisting of the last n2 numbers in L.

Explanation:

As per the information given in statement 1, 17 is a mode for L1 and 17 is a mode for L2.

Therefore, we can infer that ,

17 must occur in L1, either same or a greater number of times as any other number in L1.
17 must occur in L1, either same or a greater number of times as any other number in L2.

As all elements in L are in ascending order, we can also conclude that

Each number between last occurrence of 17 in L1 and the first occurrence of 17 in L2 must be equal to 17 only.
Therefore, 17 occurs either same or greater number of times as any other number in L.
Thus, 17 is a mode for L.

However, from this statement, we cannot conclude anything about the mode of L1, L2, or L.

Hence, statement 2 is not sufficient to answer the question.

Therefore, 17 is a mode for L1 and 17 is a mode for L2.
