Directions: Reading Comprehension - read the following passage to answer the question below.

Neutrinos are ubiquitous but ghostly, nearly massless particles produced by suns and supernovas. They normally flit through the universe passing unimpeded through matter, including our bodies, without leaving a trace of their existence.

But at the bottom of the Soudan mine, scientists have sunk hundreds of tons of metal dubbed MINOS, the Main Injector Neutrino Oscillation Search. Its job is to detect some of the particles being beamed through the ground toward Minnesota by an accelerator at Fermi Lab about 456 miles away.

When MINOS scientists decided to measure how long that trip took, they came up with something curious. A beam of light should take about 2.5 milliseconds (or thousandths of a second) to get from Fermi Lab in Batavia, Ill., to Soudan. But the neutrinos seemed to be arriving just a tiny bit sooner, beating light by about 126 nanoseconds (or billionths of a second), according to a 2007 study.

Which of the following statements is NOT supported by the passage?


A

The Fermi Lab is in Illinois.

B

The neutrinos were estimated to arrive 126 nanoseconds sooner than a beam of light would have.

C

The neutrinos were expected to take 2.5 milliseconds or less to travel the distance between the Fermi Lab and the MINOS location in the Soudan mine.

D

Neutrinos are produced by the sun and supernovas.

E

MINOS stands for Main Injector Neutrino Oscillation System.
