Last year a global disturbance of weather patterns disrupted harvests in many of the world’s important agricultural areas. Worldwide production of soybeans, an important source of protein for people and livestock alike, was not adversely affected, however. Indeed, last year’s soybean crop was actually slightly larger than average. Nevertheless, the weather phenomenon is probably responsible for a recent increase in the world price of soybeans.

Which of the following, if true, provides the strongest justification for the attribution of the increase in soybean prices to the weather phenomenon?

India, like Italy and China, has no single dominant cuisine:  Indian food comprises many different styles of cooking, with each a product of their regional influences, from the fiery vegetarian dishes of the south to the Portuguese-influenced Goan cooking of the west, to the more familiar Mogul food of the north.
请问这个with为什么不可以修饰different styles呢，我看之前的解答，说的是这个with只能表达有，用什么方式之类的意思，不能指前面一样的东西，我不太懂，这里不是对前面这个different styles的解释吗，然后B的Its有指代错误吗~
