Analyzing Data Sufficiency for Kitchen Granite Colour

This is a data sufficiency question. We are given a question about the colour of the granite in the kitchen and two statements. We need to determine if either statement alone, or both statements together, are sufficient to definitively answer the question.

Evaluating Statement 1: Granite Colour vs. Wall Colour

Statement 1 says: The colour of the granite is the colour of the wall.

This statement tells us that the granite and the wall share the same colour. However, it does not specify what that shared colour is. The wall could be red, blue, green, black, white, or any other colour. Since we don't know the wall's colour, we cannot determine the granite's colour from this statement alone.

• Statement 1 provides a relationship between the granite's colour and the wall's colour but does not give the specific colour itself.
• Therefore, Statement 1 alone is not sufficient to answer the question "What is the colour of the granite in the kitchen?".

Evaluating Statement 2: Brightness of Granite Colour

Statement 2 says: The colour of the granite is very bright.

This statement describes a characteristic of the granite's colour – its brightness. It tells us the colour is not dull or muted. However, many different colours can be bright, such as bright red, bright yellow, bright blue, bright green, etc. This statement narrows down the *type* of colour (bright) but does not identify the specific colour.

• Statement 2 gives a quality of the granite's colour (brightness) but not the colour itself.
• Therefore, Statement 2 alone is not sufficient to answer the question "What is the colour of the granite in the kitchen?".

Evaluating Statements 1 and 2 Combined

Now let's consider both statements together:

• Statement 1: The colour of the granite is the colour of the wall.
• Statement 2: The colour of the granite is very bright.

Combining these, we know that the granite's colour is the same as the wall's colour, and this shared colour is very bright. This means the wall is also a very bright colour. Examples of colours that fit this description could be bright yellow, bright red, bright blue, bright green, etc. We still don't know *which* specific bright colour it is.

Even with both pieces of information, there are multiple possible bright colours the granite could be. Therefore, combining Statement 1 and Statement 2 is also not sufficient to answer the question.

Conclusion on Data Sufficiency

Based on the analysis of each statement alone and both statements together, neither provides enough information to definitively determine the exact colour of the granite in the kitchen.

Therefore, neither Statement 1 nor Statement 2 is sufficient to answer the given question.

Additional Information on Sufficient and Insufficient Statements

In data sufficiency problems, the goal is not necessarily to find the answer to the question itself, but rather to determine if the provided data is capable of leading to a single, unique answer. If a statement or combination of statements leads to more than one possible answer, it is considered insufficient.

• If Statement 1 alone gives a unique answer, it is sufficient.
• If Statement 2 alone gives a unique answer (regardless of Statement 1), it is sufficient.
• If neither Statement 1 nor Statement 2 alone gives a unique answer, but both together do, then both combined are sufficient.
• If even both statements together do not give a unique answer, then neither statement is sufficient.

In this specific problem about the granite colour, neither statement individually, nor both together, pin down a single colour. The information provided is always consistent with multiple possible colours (e.g., bright red or bright blue). Therefore, the statements are insufficient.
