一道SAT语法题!
The development of telescopes of greater power and resolution (has given) astronomers hope that glimpses of distant solar system bodies even (smaller than) Pluto (will soon) (be possible).(No error)
这句是No error.但是这句为什么用has given现在完成时阿?

我这样理解的：
这句话是说“大功率望远镜的发展和解决给了天文学家希望.”,大功率望远镜的发展和解决这件事是已经发生了,并产生了影响（给了天文学家希望）,用现在完成时没错啊,你可以把前面这个主语用that代替：That（The development of telescopes of greater power and resolution）has given astronomers hope that .
你认为呢?
