Practice Questions: Problem Scoping | Artificial Intelligence (AI) for Class 9 PDF Download

Q1. Which of the following is the first stage of the AI Project Cycle?
(a) Modelling
(b) Evaluation
(c) Problem Scoping
(d) Data Acquisition

Ans: (c) Problem Scoping
Problem Scoping is the first step where the problem to be solved is identified and framed clearly.

Q2. What is the main purpose of the 'Modelling' stage in the AI project cycle?
(a) To collect data
(b) To deploy the solution
(c) To develop AI algorithms based on the explored data
(d) To clean the data

Ans: (c) To develop AI algorithms based on the explored data
In the modelling phase, AI algorithms are built using the prepared and explored data to solve the identified problem.

Q3. In the CottonAce app example, what type of data was collected during Data Acquisition?
(a) Only pest images
(b) Farmer names, pesticide usage, and images of pests
(c) Video recordings of pests
(d) Only cotton crop yield numbers

Ans: (b) Farmer names, pesticide usage, and images of pests
Data collected included images of pests, farmer names, village names, farm size, and pesticide usage.

Q4. Which stage involves analyzing the data for patterns and trends?
(a) Deployment
(b) Problem Scoping
(c) Data Exploration
(d) Evaluation

Ans: (c) Data Exploration
Data Exploration is about identifying patterns and trends in the collected data to help inform modelling decisions.

Q5. What was the main problem faced by cotton farmers as described in the textbook?
(a) Too much rain damaging the crops
(b) Inability to harvest cotton on time
(c) Pest infestation by Pink Bollworm
(d) Lack of proper seeds

Ans: (c) Pest infestation by Pink Bollworm
Cotton crops were frequently infected with the Pink Bollworm, which was hard to detect and control by small farmers.

Q6. What is the purpose of the Evaluation phase in the AI Project Cycle?
(a) Deploying the final AI model
(b) Identifying trends in raw data
(c) Testing the performance and accuracy of the model
(d) Selecting the problem

Ans: (c) Testing the performance and accuracy of the model
Evaluation ensures the AI model works as intended and helps in refining it before deployment.

Q7. Which of the following is NOT a part of the 4Ws Problem Canvas?
(a) Who
(b) What
(c) When
(d) How

Ans: (d) How
The 4Ws are Who, What, Where, and Why. "How" is not included in the 4Ws canvas.

Q8. What is the goal of Problem Scoping in an AI project?
(a) Train the AI model
(b) Develop the AI app
(c) Identify and define the problem to be solved
(d) Deploy the solution

Ans: (c) Identify and define the problem to be solved
Problem Scoping helps clearly define what problem the AI project is going to address.

Q9. How did the CottonAce app benefit the farmers?
(a) Reduced smartphone usage
(b) Increased rainfall
(c) Reduced pesticide costs and improved profit margins
(d) Increased dependence on technology

Ans: (c) Reduced pesticide costs and improved profit margins
The app led to a drop in pesticide costs by 38% and increased profit margins by up to 26.5%.

Q10. Why is it important to use a Problem Statement Template in AI projects?
(a) To list all types of AI models
(b) To summarize the 4Ws of problem scoping
(c) To learn coding
(d) To collect farmer details

Ans: (b) To summarize the 4Ws of problem scoping
The template helps summarize stakeholders, problem, context, and the benefit of the solution in a structured way
