Assertion (A): Data acquisition is crucial for an AI system to function effectively.

Reason (R): Without the correct data, an AI system cannot make accurate predictions or decisions.

Based on the above assertion and reasoning, pick an appropriate statement from the options given below:

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true and R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
5. Both A and R are false.

Structured data is well-organised and easily searchable data, typically found in databases or spreadsheets (such as Microsoft Excel). This data is arranged in rows and columns, making it straightforward to input, store, retrieve, and analyse. For instance, your school's timetable is a form of structured data, with rows representing each class and columns containing details like subject, teacher, and time. This arrangement facilitates efficient data management and retrieval.

Based on the above paragraph, answer the following questions:

(a) What is structured data?

1. Data that has no specific format
2. Data that is well-organised and easily searchable
3. Data that cannot be stored in databases
4. Data that is difficult to retrieve and analyse

(b) Where is structured data typically found?

1. In random text files
2. In handwritten notes
3. In databases or spreadsheets
4. In video files

(c) What is the purpose of arranging data in rows and columns?

1. To facilitate efficient data management and retrieval
2. To make it easier to delete
3. To make it look visually appealing
4. To prevent data from being edited

(d) How is structured data usually arranged?

1. In paragraphs and sentences
2. In a timeline format
3. In rows and columns
4. In graphical format
