Often incorrectly referred to as a tidal wave, a tsunami, a seismic sea wave that can reach up to 150 miles per hour in speed and 200 feet high, is caused by underwater earthquakes or volcanic eruptions.

A.  up to 150 miles per hour in speed and 200 feet high, is
B.  up to 150 miles per hour in speed and heights of up to 200 feet, is
C.  speeds of up to 150 miles per hour and 20 feet high, are
D.  speeds of up to 150 miles per hour and heights of up to 200 feet, is
E.  speeds of up to 150 miles per hour and as high as 200 feet, are

正确答案是d。但我不明白为什么前面那么多个tidal wave， tsunami，seismic sea这些名词，后面的is caused而不是are caused.

“Often incorrectly referred to as a tidal wave”是“a tsunami”的修饰语。“a seismic sea wave ”是“a tsunami”的同位语，“that...“是“a seismic sea wave ”的定语。 所以“a tsunami”是is的主语，其它名词都是用来修饰“a tsunami”的。
