Thus, you cannot use this expression to present reason for an action in the clauseRULE 2: ‘Due to’ is correct if the sentence makes sense when you replace ‘due to’ with ’caused by’. If, it does not, then use of ‘due to’ is not correctRule 3: The expression ‘because of’ is used to modify entire clauses. Thus, you can use this expression to present reason for an action in the clause.Example:
The parent-teacher meeting was canceled due to heavy rains. – INCORRECT
‘Due to’ modifies the action in the preceding clause and hence is not used correctly.The parent-teacher meeting was canceled caused by heavy rains. – INCORRECT
Note how when “due to” is replaced with “caused by”, the sentence no longer makes sense.The parent-teacher meeting was canceled because of heavy rains. – CORRECT
‘because of’ modifies the action in preceding clause, indicating why the meeting was canceled.The cancellation of parent-teacher meeting was due to heavy rains. – CORRECT
‘Due to’ modifies the noun – cancellation.The cancellation of parent-teacher meeting was caused by heavy rains.- CORRECT
Note how when “due to” is replaced with “caused by”, the sentence makes complete sense.

1.这个选项太过中文话，plunging用像形容词，并且有一种是manufacturer plunge的感觉
2.gmat讲究逻辑顺序，因此过度供应导致的价格下跌，比较符合逻辑一些

due to + 名词；
原义逻辑：因为过度供应导致价格猛降，生产商已经宣布会降低生产...但这句话没有很能体现这个逻辑

due to 只能修饰名词
而且 from an oversupply 的原因意味也不是很强

due to 后面只能修饰名词

cause
overproductionresult
the manufacturer has announced that it will cut production

from怪怪的
because可以放在句首

plunging computer chip prices from an oversupply 语义不清晰

plunging, 有manufacturer 发出的动作之嫌

due to 后面只能修饰名词
