The sequence of instructions for solving a problem is known as ______________.
Correct Answer
C. Algorith
Explanation
The sequence of instructions for solving a problem is known as an algorithm. An algorithm is a step-by-step procedure or a set of rules to be followed in order to solve a specific problem or achieve a particular goal. It provides a clear and systematic approach to problem-solving, allowing for efficient and effective solutions to be developed.

3.
____________ is an example for LOGO command.
Correct Answer
B. RT
Explanation
RT is an example of a LOGO command. LOGO is a programming language that was designed for educational purposes. RT stands for "right turn" and is used to rotate the turtle (a graphical cursor) in the LOGO programming environment. This command is used to change the direction in which the turtle is facing, allowing for the creation of various shapes and patterns.
4.
The turtle always moves in the direction that its ___________ is pointing.
Correct Answer
B. Head

8.
This LOGO procedure will draw a circle.repeat 360[rt 4 fd 6]
Correct Answer
A. True
Explanation
The given LOGO procedure uses a repeat loop to draw a circle. The loop repeats 360 times, with each iteration turning the turtle right by 4 degrees and moving it forward by 6 units. Since a circle has 360 degrees, this procedure will effectively draw a circle. Therefore, the correct answer is True.
9.
The command in logo are case sensitive.
Correct Answer
B. False
Explanation
Logo is a programming language that is not case sensitive. This means that the command "forward" is the same as "FORWARD" or "Forward". Therefore, the statement "The command in logo are case sensitive" is false. In Logo, the commands can be written in any combination of uppercase and lowercase letters.
10.
To move the turtle forward which command is used?
Correct Answer
D. Both (i) and (iii)
Explanation
Both (i) and (iii) are correct answers because in the turtle graphics library, the command "Fd" and the command "Forward" are both used to move the turtle forward. The "Fd" command is a shorthand notation for "Forward" and they both perform the same function of moving the turtle in the forward direction.
11.
By default what is the color of lines draw by turtle?
Correct Answer
C. Black
Explanation
By default, the color of lines drawn by the turtle is black. This means that when the turtle moves and creates lines on the screen, those lines will appear in black color.
12.
Correct the error in FD50
Correct Answer
D. FD 50
Explanation
The correct answer is "FD 50" because it follows the correct format of the other options provided. The correct format consists of two letters followed by a space and then a number. The other options either have incorrect characters or do not follow the specified format.
13.
Which command is used to move the turtle backward?
Correct Answer
D. Both (i) and (ii)
Explanation
Both (i) and (ii) are correct answers because the command "BK" and the command "BACK" can both be used to move the turtle backward. The command "BK" is a commonly used abbreviation for "BACK" and is recognized by most turtle graphics systems. Therefore, both commands can be used interchangeably to achieve the desired result of moving the turtle backward.
14.
What is used by turtle to draw line?
Correct Answer
C. Pen
Explanation
The turtle uses a pen to draw a line. The pen is an essential tool for the turtle as it allows it to leave a visible mark on the canvas or screen while moving. The turtle can control the pen's attributes such as color, thickness, and style to create different types of lines and shapes. Therefore, the correct answer is "Pen."
15.
Which command is used to erase the line?
Correct Answer
D. Both (ii) and (iii)
Explanation
Both (ii) and (iii) are correct answers because the command "PENERASE" and its abbreviation "PE" are both used to erase a line. The command "ERASE" is not mentioned in the options, so it is not a correct answer.
