Explanation:

Question 1

In Python, when you add an int (integer) and a float (floating - point number), the result is a float. The type() function returns the data type of its argument. So, 5+2.5 = 7.5 which is a float.

In Python, a dictionary is defined using curly braces {}. The first option ["name":"Alice", "age":20] uses square brackets [] (which are for lists) instead of curly braces. So it is an invalid dictionary.

The len() function in Python returns the number of elements in a sequence. The list [1,2,2,3,3] has 5 elements.

Answer:

float
