雅思剑桥5 阅读的一个题目应该是TRUE还是NOT GIVEN

原文中说：
experts analyse fragments found minute crystals of nickel sulphide trapped inside the glass had almost certainly caused the failure。

题目说：
Little doubt（几乎没有疑问） was expressed about the reason BW accident

其中Little doubt=almost certainly
reason=minute crystals of nickel sulphide trapped inside the glass

the failure=BW accident

动词方向一致
根据新东方总结的三点法，3点1样则为TURE
所以本题为TURE
