. A user asks an AI chatbot, "Tell me about history." The response is very broad
and not useful. What is the primary risk demonstrated by this poor prompt?
A) Increased data usage
B) Biased information
C) Imprecise results
D) Outdated information
Correct Answer: C) Imprecise results
Rationale: Vague prompts like "Tell me about history" lead to imprecise or irrelevant
outputs because they fail to clearly communicate the user's intent .
2. Which component of a prompt provides the AI with background information
and relevant facts to narrow the scope of the query?
A) Persona
B) Context
C) Output format
D) Instruction
Correct Answer: B) Context
Rationale: Context gives relevant background that shapes how the AI interprets and
answers the query .
3. What is the primary advantage of writing highly detailed and descriptive
prompts?
A) Increased creative randomness
B) Facilitation of more accurate responses
,C) Faster response generation speed
D) Reduced computational cost
Correct Answer: B) Facilitation of more accurate responses
Rationale: Clear detail guides the model toward the intended output, resulting in more
accurate responses .
4. What is a key benefit of assigning a specific "persona" (e.g., "You are an expert
nutritionist") to an AI?
A) Enhanced memory of past conversations
B) Greater response speed
C) More user-friendly and targeted interactions
D) It eliminates the risk of hallucinations
Correct Answer: C) More user-friendly and targeted interactions
Rationale: Persona helps tailor tone and style, making responses more appropriate for the
situation .
5. If a prompt lacks clarity and specificity, what is the most likely negative
outcome?
A) The AI will refuse to answer
B) The query will be misunderstood
C) The AI will generate a long response
D) The AI will correct the prompt
Correct Answer: B) The query will be misunderstood
Rationale: Neglecting clarity and specificity in a prompt can lead to the query being
misunderstood .
6. Which method of prompt engineering expects a generalized response from a
language model because there are no relevant training examples given in the
prompt?
,A) Cognitive verifier pattern
B) Zero-shot prompting
C) Generated knowledge
D) Chain of Thought (CoT)
Correct Answer: B) Zero-shot prompting
Rationale: Zero-shot prompting relies purely on instructions without sample
inputs/outputs .
7. A prompt asks the AI to solve a math problem and includes the instruction,
"Explain your reasoning step by step." This demonstrates which technique?
A) Generated Knowledge
B) Chain of Thought (CoT)
C) Few-shot
D) Persona modification
Correct Answer: B) Chain of Thought (CoT)
Rationale: Chain-of-Thought prompting asks the model to show its reasoning step by step
before providing a final answer .
8. A company that specializes in financial advice wants to implement AI to improve
business processes. Which task is an AI system well-suited for in this context?
A) Reading client's facial expressions
B) Summarizing documents
C) Eliminating asset risk
D) Generating new products
Correct Answer: B) Summarizing documents
Rationale: AI systems are well-suited for summarizing documents and extracting key
information from lengthy texts .
, 9. A company is developing new software for programming and wants to
incorporate AI. Which software task is well-suited for AI?
A) Explaining code errors
B) Defining code variables
C) Specifying project structure
D) Performing user testing
Correct Answer: A) Explaining code errors
Rationale: AI is well-suited for explaining code errors and assisting with programming
tasks .
10. Which key benefit is associated with artificial intelligence?
A) Implementing common sense
B) Predicting beyond training data
C) Performing independent reasoning
D) Processing data in real time
Correct Answer: D) Processing data in real time
Rationale: AI systems are valuable for processing data in real time, enabling rapid analysis
and decision-making .
11. What should a person do first when creating an AI prompt for song lyrics?
A) Record the completed version of the song
B) Choose a specific topic for the song
C) Finalize the melody for the song
D) Write a rough draft of the song lyrics
Correct Answer: B) Choose a specific topic for the song
Rationale: Before crafting a prompt, the user should clearly define the topic to guide the
AI's creative process .
