问题 Scientists reported last month on a sign of relative solar_______: the solar wind, a rush of charged particles continually spewed from the Sun at a million miles an hour, had diminished to its lowest level in 50 years.
A. quiescence
B. turbulence
C. isolation
D. calm
E. remoteness
F. instability
选项
答案A，D
解析 -方程等号：冒号，同义重复。
-强词和对应：冒号后面说太阳风降到了近50年以来的最低值，冒号前面说科学家报道了上个月太阳活动相对空格的迹象，强词是diminished to its lowest降到了最低级，指向空格，根据冒号前后取同。选项里面有两组同义词，第一组是quiescence与calm平静，第二组是turbulence与instability混乱，所以答案选择AD。其他选项，isolation隔离，remoteness遥远。
