原文:Variables which are static and which are initialized only have their
initial value assigned once during the program’s execution. Thus, they can be
preferable over initialized auto objects which are assigned a value every time
the block in they are defined begins execution.
問題主要是在第二句，which are assigned a value every time the block in 感覺後面
不應該直接+they(這邊的they我也不清楚是initialized auto abject還是 static
variables)
they are defined begins execution. 這邊不是應該要+一個to嗎?

少了which: the block (in which they are define)這個they 是指init. auto objects

謝謝，多一個which我就懂它的文法結構了
