Answer
High-performance liquid chromatography (HPLC) is a technique that can effectively separate sugars based on their different interactions with the stationary phase and the mobile phase. This method allows for precise separation and quantification of complex mixtures, making it ideal for separating the two different sugars present in a honey extract.

Answer
Atomic absorption spectroscopy is primarily used to analyze the concentration of metal ions in a sample. It is not suitable for separating sugars, which are organic compounds.

Answer
UV-visible spectrophotometry is useful for quantifying substances that absorb ultraviolet or visible light. While it can identify sugars, it does not provide the separation needed for two different types of sugars found in honey.

Answer
Flame tests are used to identify the presence of certain metal ions based on the color they emit when heated in a flame. This method is not applicable for separating sugars.
