Definition: In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.
Input: Question: What country did the storm stall off the coast of around November 6th? Passage:On November 4, an extratropical disturbance was spawned just off the coast of western France, within a cold front, by another extratropical cyclone to the north, named "Quinn." This storm began causing heavy rainfall in northern Italy, leading to flooding in the region. On the next day, a low-pressure area formed over western France, and the system was named Rolf by the Free University of Berlin, which names all significant low pressure systems affecting Europe. As the storm slowly moved eastward, it caused flooding in the Balearic Islands. Rolf gradually organized, and convection began to increase in the storm. Over the next couple of days, the storm continued to organize as it moved eastward, approaching the northwestern coast of Italy. On November 5, Rolf's forward motion slowed while the storm was stationed above the Massif Central in southern France, maintaining a central pressure of . On November 6, the system moved into the western Mediterranean Sea and stalled off the coast of Liguria, while gradually strengthening, bringing additional flooding to the region. Around the same time, the storm's frontal structure shrunk to in length. During that evening, Rolf spawned a tornado over Alassio, in northern Italy, causing some structural damage. On November 7, 2011, Rolf turned westward and slowly transitioned from an extratropical system into a subtropical depression over the warm waters of the Mediterranean Sea, with the system acquiring a warm quasi-symmetric core, and with organized convective rainbands wrapping around the center of the storm. The storm was then given the designation Invest 99L, by the United States Naval Research Laboratory (the NRL). The NOAA also began watching the subtropical depression, which was now located in the Gulf of Lion. Later that day, Rolf transitioned from a subtropical depression into a tropical depression off the coast of France, and the NOAA gave Rolf the identifier 01M.
