Do you think the Oklahoma City events described in the article give adequate proof of the scientists’ concerns? Explain why or why not? (Not Biology, It's Earth Science)

Explanation:

Twenty years ago, on 19 April 1995, a disaffected veteran named Timothy McVeigh drove a Ryder truck stuffed with explosives into downtown Oklahoma City and destroyed a federal office building, killing 168 people, including 19 children, and maiming hundreds of others. That much we know.

We also know that, within 90 minutes of the bombing, McVeigh was pulled over near the Kansas border and arrested, alone, at the wheel of a glaringly improbable getaway car, an ancient, spluttering rust bucket of a Mercury sedan with no licence plates, which made him a sitting duck for any passing highway patrolman.

How could such a callous, carefully planned attack have come to such an incongruously slapdash end? After a vast investigation headed by the FBI, three trials mounted against McVeigh and his co-conspirator, Terry Nichols, and an avalanche of court documents, there is still no definitive answer to that question.

Explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
