EOU Assessment: 1.2 Selection and Logic in Flowcharts

A. Fill in the Blanks

Word Bank: Diamond, Boolean, Selection, Condition, Modulus, Flowchart

1. A programming decision-making structure that lets an algorithm choose between different paths of code is called a statement.

2. In a flowchart, a selection statement or decision box is represented by a shape.

3. A question or statement inside a decision box that evaluates to either True or False is called a .

4. Systems of logic that produce only binary outputs (True or False) are known as logic.

5. The arithmetic operator % returns the remainder after division and is called the operator.

B. Multiple Choice Questions

6. Which comparison operator checks if two values are not equal to each other in Python programming?

a) ==

b) =

c) !=

d) <=

7. What will the expression (10 > 5) AND (3 > 8) evaluate to?

a) True

b) False

c) Maybe

d) Syntax Error

8. Which Boolean operator requires at least one individual condition to be true for the entire expression to evaluate as true?

a) AND

b) NOT

c) OR

d) MOD

9. If x = 5, what is the result of the arithmetic increment operation x++?

a) 4

b) 5

c) 6

d) 10

10. Unlike strict binary Boolean logic, what concept in computer science/mathematics allows continuous values between 0 (false) and 1 (true) to describe spectrums like temperature ("warm", "chilly")?

a) Selection Logic

b) Fuzzy Logic

c) Binary Logic

d) Sequential Logic

11. What are the three core structural components of an IF...THEN...ELSE selection statement?

a) Input, Output, Stop

b) Condition, True path action, False path action

c) Diamond, Parallelogram, Rectangle

d) Start, Variable, Loop

12. What is the primary function of the NOT logic operator?

a) Combines two conditions into one.

b) Reverses or flips the Boolean value of a condition.

c) Checks if a number is greater than another.

d) Divides two numbers and finds the remainder.

C. One-Word Answers

13. Name the British mathematician from the 1800s after whom True/False computational logic is named.

Checking if two entered passwords match exactly.

Logging in: Username == Correct AND Password == Correct.

Evaluating if a student passed: Score >= 40.

Reversing an alarm state: NOT (Door == Open).

Determining if a number is even: Number % 2 == 0.

E. Arrange in Proper Sequence

Order the following steps logically from first (1) to last (4).

22. Logical Order of Executing an IF...THEN...ELSE Block in a Program:

Follow the ELSE branch and execute the alternative actions.

Evaluate the given Boolean Condition as True or False.

Receive user data input.

Branch down the THEN path if the condition is True.

23. Flowchart Execution Sequence for a Library Book Discount System:

Input student age and library card status.

Output "Standard Rate".

Evaluate Age < 12 OR HasStudentCard == True in the diamond box.

Output "Discount Applied".

F. True or False

State whether the statement is True or False. If False, provide a one-sentence correction.

24. An OR operator outputs False only when all individual conditions being tested evaluate to False.

True False

25. In flowcharts, a selection diamond box can have three or four exit arrows for True, False, Maybe, and Error.

True False

26. The comparison operator > means "less than".

True False

27. A Boolean expression can return three possible outputs: True, False, or Neutral.

True False

28. The code 17 % 5 results in an answer of 2.

True False

29. In Scratch or flowchart algorithms, a branching decision statement asks a question with only two possible outcomes.

True False
