Session 0: Module A Historical Context & Evolution - Test Solutions¶
📝 Multiple Choice Test¶
Question 1: Early AI System Limitations¶
What was the primary limitation of early AI systems that drove the development of agentic architectures?
A) Expensive API costs
B) Limited computational power
C) Stateless, single-turn interaction model ✅
D) Lack of training data
Correct Answer: C) Stateless, single-turn interaction model
Explanation: Early AI systems were fundamentally limited by their inability to maintain context across interactions, use tools, or perform multi-step reasoning. This stateless nature meant each query was treated independently without memory or iterative capability, making them unsuitable for complex tasks requiring persistence or tool integration.
Question 2: ReAct Research Paper¶
Which research paper introduced the concept of interleaving thought and action in AI agents?
A) Constitutional AI (2022)
B) Reflexion (2023)
C) ReAct (2022) ✅
D) Toolformer (2023)
Correct Answer: C) ReAct (2022)
Explanation: The ReAct paper "Synergizing Reasoning and Acting in Language Models" introduced the groundbreaking concept of interleaving reasoning (thinking) with acting (tool use), laying the foundation for modern agentic systems. This approach enables agents to reason about when to use tools and reflect on the results.
Question 3: Memory Architecture Types¶
What are the three types of memory in modern agent semantic memory systems?
A) Short-term, long-term, cache
B) Local, distributed, cloud
C) Input, output, processing
D) Episodic, semantic, working ✅
Correct Answer: D) Episodic, semantic, working
Explanation: Modern agent memory systems implement three distinct types: episodic memory (conversation history and experiences), semantic memory (learned concepts and knowledge), and working memory (current task context and active information). This architecture enables agents to learn from experience and apply knowledge contextually.
Question 4: ChatGPT Plugins Launch¶
When did OpenAI launch ChatGPT Plugins, marking the first mainstream tool-augmented conversational AI?
A) January 2023
B) June 2023
C) March 2023 ✅
D) December 2022
Correct Answer: C) March 2023
Explanation: OpenAI launched ChatGPT Plugins in March 2023, representing the first mainstream deployment of tool-augmented conversational AI and demonstrating commercial viability of agent-like systems. This milestone marked the transition from research concepts to production-ready agent systems.
Question 5: Current Industry Adoption¶
According to current industry adoption patterns, what percentage of enterprise customer service uses agentic systems?
A) 50%
B) 40% ✅
C) 30%
D) 20%
Correct Answer: B) 40%
Explanation: As of 2024-2025, approximately 40% of enterprise customer service operations have adopted agentic systems, representing significant industry adoption of agent technologies. This adoption rate reflects the proven value of agents in handling complex customer interactions and reducing operational costs.
