Below is a text with blanks. For an each blank, there is a list of choices. Select the appropriate answer choice for each blank.

1.) On earth, snow ………………….. as we all know, form from frozen water. But ……………… believe there are also flakes that fall on Mercury and they’re made of iron. They published their findings in the journal Geophysical Research Letters. Investigators have been trying to figure out why Mercury is the only other terrestrial planet in our solar system that has a global …………………. field. It’s about one hundred times weaker than earth’s. No previous models have been able to predict what would cause this type of ………………………. So researchers at the ……………………… of Illinois and Case Western University set up an experiment to try to figure it out. They created a molten iron and sulfur mixture similar to mercury’s core. They subjected the mix to high temperatures and pressures. Then they ………………….. what happened in this Mercury model. Turns out that as the outer core cools, the iron forms what researchers call cubic “flakes” that slowly fall to the core’s center. As the iron snow falls the sulfur-rich liquid rises. Researchers believe these ……………….. produce the weak magnetic fields and mercury’s iron snow.

2.) Anyone who’s ever cut up an onion knows that some smells can ………………… be painful. Now researchers form Baltimore and Denver are closer to understanding why ………………. used to think that odors that are……………… like onion and ammonia, directly ………………….. the trigeminal nerve. That nerve responds to touch, temperature and painful ………………….. all over the head and its fibers extend to the ………….. that line the inside of the nose. But the current study suggests that the trigeminal nerve doesn’t act alone. Specialized chemonsensory cells that line the nasal cavity are actually the first to detect irritating smells. They pass the news to the trigeminal nerve, which then lets your brain know that it’s time to feel the burn. And to tear, or cough, or gag or just generally back off. The findings are described in the March issue of the Journal of Neurophysiology. Having these special sensory cells as a go between, the scientists say, might make our noses sensitive to a broader variety of irritating odors. that may not seem like such a bonus. But the system probably evolved to protect us., by giving us a heads up when we run into ………………. noxious. It may also keep us from adding too many onions to the spaghetti sauce.
