,Question 1 of 77
Convert the decimal number 23.375 to binary. Which of the following is its correct binary
representation?
A. 10111.011
B. 10111.101
C. 10011.011
D. 10111.110
The correct answer is:
Correct Action: 10111.011
Rationales
• 10111.011 (Correct):
This is the correct action. 23 in binary is 10111 (16+4+2+1). 0.375 in binary is 0.011 (0.5*0 + 0.25*1 + 0.125*1 = 0.375).
Combined: 10111.011. Option B has fraction 0.625, C has integer 19, D has fraction 0.75.
• 10111.101 (Incorrect):
This option is not appropriate. 0.375 in binary is 0
• 10011.011 (Incorrect):
This option is not appropriate. 0.375 in binary is 0
• 10111.110 (Incorrect):
This option is not appropriate. 0.375 in binary is 0

,Question 2 of 77
A researcher wants to find documents that discuss either 'machine learning' or 'artificial
intelligence' but must also include 'ethics' and not include 'deep learning'. Which Boolean query
correctly represents this search?
A. (machine learning OR artificial intelligence) AND ethics NOT deep learning
B. (machine learning OR artificial intelligence) AND ethics AND NOT deep learning
C. (machine learning AND artificial intelligence) OR ethics NOT deep learning
D. machine learning OR artificial intelligence AND ethics NOT deep learning
The correct answer is:
Correct Action: (machine learning OR artificial intelligence) AND ethics AND NOT deep learning
Rationales
• (machine learning OR artificial intelligence) AND ethics AND NOT deep learning (Correct):
This is the correct action. Option B correctly uses parentheses for the OR group, then AND with ethics, and AND NOT to
exclude deep learning. Option A lacks an explicit AND before NOT, which may be ambiguous. Options C and D misgroup
terms, leading to incorrect results.
• (machine learning OR artificial intelligence) AND ethics NOT deep learning (Incorrect):
This option is not appropriate. Option A lacks an explicit AND before NOT, which may be ambiguous. Options C and D
misgroup terms, leading to incorrect results
• (machine learning AND artificial intelligence) OR ethics NOT deep learning (Incorrect):
This option is not appropriate. Option A lacks an explicit AND before NOT, which may be ambiguous. Options C and D
misgroup terms, leading to incorrect results
• machine learning OR artificial intelligence AND ethics NOT deep learning (Incorrect):
This option is not appropriate. Option A lacks an explicit AND before NOT, which may be ambiguous. Options C and D
misgroup terms, leading to incorrect results

, Question 3 of 77
Consider the following recursive function f(n) where n is a non-negative integer. What is the output
of f(5)?
def f(n):
if n < 2:
return n
else:
return f(n-1) + f(n-2)
A. 5
B. 8
C. 13
D. 21
The correct answer is:
Correct Action: 5
Rationales
• 5 (Correct):
This is the correct action. This implements the Fibonacci sequence: f(0)=0, f(1)=1, f(2)=1, f(3)=2, f(4)=3, f(5)=5. Option A
is correct; B is f(6), C is f(7), D is f(8).
• 8 (Incorrect):
This option is not appropriate. Option A is correct; B is f(6), C is f(7), D is f(8).
• 13 (Incorrect):
This option is not appropriate. Option A is correct; B is f(6), C is f(7), D is f(8).
• 21 (Incorrect):
This option is not appropriate. Option A is correct; B is f(6), C is f(7), D is f(8).
