Question

drag the right word to its synonyms
manner,
system,
way
method
hypothesis
placebo

Explanation:

To solve this, we analyze the meanings: "manner", "system", "way" and "method" all relate to a mode of doing something (synonyms for approach/way). "hypothesis" is a proposed explanation, "placebo" is a dummy treatment, neither are synonyms for the blue group. So "method" should be dragged to the blue circle with "manner, system, way".

Answer:

Drag "method" to the blue circle containing "manner, system, way".
