Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1, i.e., melts; surround.
Filler Concept: Scientific explanation using correct verb and contextual vocabulary
Grammar Explanation:
Melts fits the scientific context, as sugar dissolving resembles melting in layman's terms.
Surround logically follows, as water molecules surround and interact with the sugar molecules to break their bonds.
The other options (vanish–limit, soften–grid, disappear–edge) are either incorrect in meaning or do not fit the scientific explanation.
Correction: Sugar melts in water because it is made up of molecules of sucrose, a compound held together by relatively weak bonds. When the sucrose molecules mix with water, the water molecules surround and break the bonds holding together the sugar molecule.
Final Sentence: Sugar melts in water because it is made up of molecules of sucrose, a compound held together by relatively weak bonds. When the sucrose molecules mix with water, the water molecules surround and break the bonds holding together the sugar molecule.
Conclusion: The correct option is melts; surround
