Correct Option: C (4)
Step-by-Step Explanation:
-
Understanding the Question: The question asks for the number of cells that contain data in row 1 of the provided Excel table. Row 1 is the first row of the table, which contains the headers for the columns.
-
Identifying Row 1: In the given table, row 1 consists of the following cells:
- Cell A1: "BOOKS"
- Cell B1: "SUPPLIED"
- Cell C1: "TO SENIOR"
-
Cell D1: "HIGH SCHOOL"
-
Counting Non-Empty Cells: We need to count how many of these cells contain actual data (i.e., they are not empty):
- A1 contains "BOOKS" (not empty)
- B1 contains "SUPPLIED" (not empty)
- C1 contains "TO SENIOR" (not empty)
- D1 contains "HIGH SCHOOL" (not empty)
All four cells (A1, B1, C1, D1) contain data.
- Final Count: Therefore, the total number of cells in row 1 that contain data is 4.
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 all four cells in row 1 contain data.
-
Option B (3): This option suggests that three cells contain data. This is also incorrect as we have confirmed that all four cells are filled with data.
-
Option D (5): This option suggests that five cells contain data. However, there are only four cells in row 1 (A1, B1, C1, D1). Therefore, this option is incorrect.
Common Pitfalls:
- Miscounting Cells: A common mistake is to overlook the number of cells or miscount them. Always ensure to count each cell individually.
- Confusing Rows and Columns: Make sure to identify the correct row or column when answering questions about data in Excel tables.
Revision Summary:
- Row 1 of the table contains four cells with data: "BOOKS", "SUPPLIED", "TO SENIOR", and "HIGH SCHOOL".
- The correct answer is C (4), as all four cells are filled.
- Always double-check your counts to avoid miscounting.
- Be clear about the distinction between rows and columns when analyzing data in tables.
