LangChain - Conversational RAG

Given the following code snippet, what will be the output after the second question?

from langchain.chains import ConversationChain
from langchain.memory import ConversationBufferMemory

llm = SomeLLM()
memory = ConversationBufferMemory()
chain = ConversationChain(llm=llm, memory=memory)

print(chain.run("What is AI?"))
print(chain.run("And how does it learn?"))

AThe memory will reset after each question

BThe second answer will ignore the first question

CThe second answer will consider the first question's context

DThe code will raise a syntax error

Step-by-Step Solution

Solution:

Step 1: Understand ConversationBufferMemory behavior
This memory stores conversation history and passes it to the LLM for context.
Step 2: Analyze the chain.run calls
The second call to run uses the stored history, so the answer will reflect the first question's context.
Final Answer:
The second answer will consider the first question's context -> Option C
Quick Check:
Memory stores history = context-aware answers [OK]

Quick Trick: ConversationChain with memory keeps context across calls [OK]

Common Mistakes:

Assuming memory resets automatically
Thinking each run is independent
Expecting syntax errors from correct code
