Which question compares two things?

Answer and explanation

Correct answer: In which does sugar dissolve faster hot or cold water?

The direct answer is A: in which water—hot or cold—does sugar dissolve faster? A comparison question places two conditions or objects side by side and asks how they differ. Here the two conditions are hot water and cold water, and the observed outcome is the time or speed of dissolving sugar. Option A is correct because it has two clearly named conditions. Option B asks why sugar is sweet; it seeks an explanation of taste, not a comparison between two cases. Option C asks about the appearance of water and gives no second condition. Option D asks for a reason for the cup’s beauty, which is subjective and does not compare two measurable situations. A proper investigation would use similar amounts of sugar and water, similar stirring, and suitable temperatures, then compare the dissolving times. The temperature is the factor being compared, and dissolving time is the result observed. Exam cue: words such as “hot or cold”, “which is greater”, or “which is faster” often signal comparison.
