Explanation:

1. Analyze the sentence "For some people who believe Andrew Irvine was the first person to reach the top of Mt. Everest still look for evidence to prove it." The phrase "For some people who believe..." is a prepositional phrase and relative clause, but the main clause "still look for..." lacks a proper subject - the "for some people" structure here creates a mixed construction. It should be something like "Some people who believe... still look for..." to have a clear subject - verb relationship.
2. Analyze the sentence "The reason Irvine's pictures might still be useful after all these years is because the low temperatures on Mt. Everest would have frozen and preserved the film." The construction "The reason... is because..." is a mixed construction. The correct form should be "The reason... is that..." or rephrase it without using "because" after "is".

Answer:

The mixed constructions are in the sentences:

1. "For some people who believe Andrew Irvine was the first person to reach the top of Mt. Everest still look for evidence to prove it."
2. "The reason Irvine's pictures might still be useful after all these years is because the low temperatures on Mt. Everest would have frozen and preserved the film."
