In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

[Q]: Question: Were the teams that Romano split a season between both from the same country? Passage:Romano was signed by the Chicago White Sox as an amateur free agent in 1954. In , while playing for the Waterloo White Hawks, Romano hit 9 home runs in nine consecutive games. He accumulated 38 home runs with a .321 batting average and led the Illinois–Indiana–Iowa League with 108 runs scored and 124 runs batted in. His 38 home runs in 1955 set a league record. Romano split the season between the Vancouver Mounties and the Memphis Chickasaws. In , Romano played for the Indianapolis Indians of the American Association. The Indians' manager was former major league All-Star catcher Walker Cooper, who tutored Romano and helped to greatly improve his catching skills. Romano was called up late in the 1958 season, making his major league debut with the Chicago White Sox on September 12, at the age of 23.

[Q]: Question: How old was Michael Atiyah when he and Bott finished the Atiyah-Bott fixed-point theorem? Passage:This led to his role as collaborator over many years with Michael Atiyah, initially via the part played by periodicity in K-theory. Bott made important contributions towards the index theorem, especially in formulating related fixed-point theorems, in particular the so-called 'Woods Hole fixed-point theorem', a combination of the Riemann–Roch theorem and Lefschetz fixed-point theorem (it is named after Woods Hole, Massachusetts, the site of a conference at which collective discussion formulated it). The major Atiyah–Bott papers on what is now the Atiyah–Bott fixed-point theorem were written in the years up to 1968; they collaborated further in recovering in contemporary language Ivan Petrovsky on Petrovsky lacunas of hyperbolic partial differential equations, prompted by Lars Gårding. In the 1980s, Atiyah and Bott investigated gauge theory, using the Yang–Mills equations on a Riemann surface to obtain topological information about the moduli spaces of stable bundles on Riemann surfaces. In 1983 he spoke to the Canadian Mathematical Society in a talk he called "A topologist marvels at Physics".
