With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Many ruthenium-based oxides show some unusual properties, such as a quantum critical point behavior and exotic superconductivity (in its strontium ruthenate form), and also quite common properties, such as high-temperature ferromagnetism.
text_B: Would the great majority of magnets in a particle accelerator that works at high temperatures be likely to be made of ruthenium oxides?
NO.
