Correct Option: C (5)
Detailed Explanation:
To determine the number of cells that contain data in row 1 of the provided table, we need to analyze the contents of that specific row.
Step-by-Step Analysis:
- Identify Row 1:
-
The first row of the table is as follows:
- A: BOOK
- B: SUPPLIED
- C: TO SENIOR
- D: HIGH
- E: SCHOOL
-
Count the Non-Empty Cells:
- We will count each cell in row 1 that contains data (i.e., any text or value).
-
The cells in row 1 are:
- Cell A1: "BOOK" (contains data)
- Cell B1: "SUPPLIED" (contains data)
- Cell C1: "TO SENIOR" (contains data)
- Cell D1: "HIGH" (contains data)
- Cell E1: "SCHOOL" (contains data)
-
Total Count:
- All five cells (A1, B1, C1, D1, E1) contain data. Therefore, the total number of cells with data in row 1 is 5.
Why Other Options Are Incorrect:
-
Option A (1): This option suggests that only one cell contains data. This is incorrect because we have established that there are five cells with data in row 1.
-
Option B (3): This option implies that three cells contain data. However, as we counted, there are five cells with data, making this option incorrect.
-
Option D (7): This option suggests that there are seven cells with data. Since there are only five cells in row 1, this option is also incorrect.
Common Pitfalls:
- A common mistake might be to overlook the count of cells or misinterpret the question by thinking it refers to the total number of cells in the entire table rather than just row 1.
- Ensure to count only the cells that contain actual data and not empty cells.
Revision Summary:
- Row 1 contains five cells with data: "BOOK", "SUPPLIED", "TO SENIOR", "HIGH", and "SCHOOL".
- The correct answer is C (5).
- Always count only the non-empty cells when asked about data in a specific row.
- Be careful not to confuse the total number of cells with the number of cells containing data.
