question: 2
if the following program is supposed to put down three tennis balls, where is the logic error?
1 def place_three_ball():
2 for i in range(4):
3 put_ball()
4
5 placethreeballs()
options:
line 1
line 2
line 3
line 5

Explanation:

For Question 1:

Runtime errors occur while code runs, not during parsing. I is a runtime error (Karel acts during execution). II, III, IV are syntax errors caught before execution.

For Question 2:

• Line 1: Function name is place_three_ball(), but Line 5 calls placeThreeBalls() (mismatched names, so the defined function never runs).
• Line 2 uses range(4) which would place 4 balls, but the core logic error is the function call mismatch, as the intended function isn't invoked at all.

Answer:

1. I
2. Line 5
