The image shows a multiple-choice quiz with four questions. We need to answer the questions based on our understanding of the subjects covered. The questions are: - What does I/O stand for? - What does the programming language 'FORTRAN' stand for? - Is the expression $8 \% -4 == 8 \% 4$ True or False? - Which of these is the output of a Boolean data type?

1. Problem Description

The image shows a multiple-choice quiz with four questions. We need to answer the questions based on our understanding of the subjects covered. The questions are:

- What does I/O stand for?

- What does the programming language 'FORTRAN' stand for?

- Is the expression $8 \% -4 == 8 \% 4$ True or False?

- Which of these is the output of a Boolean data type?

2. Solution Steps

Question 1: What does I/O stand for?

I/O stands for Input/Output.

Question 2: What does the programming language 'FORTRAN' stand for?

FORTRAN stands for Formula Translation.

Question 3: Is the expression $8 \% -4 == 8 \% 4$ True or False?

The $\%$ operator is the modulo operator. The modulo operation $a \% b$ returns the remainder when $a$ is divided by $b$.

$8 \% -4$ is the remainder when 8 is divided by -

4. $8 = -4 * -2 + 0$, so $8 \% -4 = 0$.

$8 \% 4$ is the remainder when 8 is divided by

4. $8 = 4 * 2 + 0$, so $8 \% 4 = 0$.

Therefore, $8 \% -4 == 8 \% 4$ evaluates to $0 == 0$, which is True.

Question 4: Which of these is the output of a Boolean data type?

A Boolean data type represents truth values, which are typically True or False. Neither String nor Integer represents the output of a Boolean. Since the image options are limited to "String" and "Integer", this means neither is appropriate here. However, one could consider 1/0 as "Integer" as a True/False Boolean, but in that context, one could make the case that integer is an output of a boolean if it is represented as 0 or

1. String is incorrect because boolean output will not be strings. We need information on the context of the question, and there is no answer here to that question.

3. Final Answer

- I/O stands for: Input/Output

- FORTRAN stands for: Formula Translation

- $8 \% -4 == 8 \% 4$ is True

- Which of these is the output of a Boolean data type? This question doesn't have adequate answers, as it should read Boolean instead of string or Integer. But if you consider 1/0 as the "integer" value for true/false as a boolean, then the correct answer is "Integer"
