Final answer:
The Excel formula checker verifies the syntax of the formulas in a worksheet. It does not check for logical, consistency, or factual accuracy. 'Suggestion' is the word closest in meaning to 'hypothesis' as both convey a tentative idea not yet proven.
Step-by-step explanation:
The question asks which of the Excel's formula checker rules is verified when checking formulas in a worksheet. The correct answer is a) Syntax. Excel's formula checker does not evaluate logical soundness, internal consistency, or factual accuracy of the data within the formulas; instead, it checks the structure and placement of functions, references, and operators within the formula to ensure they follow the correct syntax rules that Excel can understand and execute.
In relation to the second question asked in the context, the word closest in meaning to hypothesis is d) suggestion. A hypothesis is an educated guess or proposed explanation made on the basis of limited evidence as a starting point for further investigation. This makes 'suggestion' the best choice as it conveys the not-yet-proven and tentative nature of a hypothesis, unlike 'fact,' 'law,' 'formula,' or 'conclusion' which imply a stronger level of verification or finality.
