Read the text Navigational Instruments: The Quadrant and answer the question. The quadrant is a tool that was first invented by the Greeks around the time of 240 BCE. Its name comes from the shape of the tool. It is one fourth of a whole circle, and quad means four. When this tool was originally built, it had many purposes. First, astronomers used it to determine the height of stars above the horizon. Second, land surveyors used it to measure the height of manmade creations like buildings and landforms such as mountains. Third, soldiers used the quadrant to aim weapons with accuracy.

As years passed, sailors found use for the quadrant, too. By the 16th century, sailors needed a better way to navigate their ships. In the past, they used key landmarks to find their positions. However, when exploring new lands, they had to travel through unfamiliar waters. Another challenge they faced was that at times, they were surrounded by only water and had no landmarks to follow. Luckily, many sailors understood the movement of the Pole Star, called Polaris. It moved very little because of its location above the North Pole. The height of Polaris changed depending on a ship's latitude. Latitude is the distance north or south of the equator. Knowing how high Polaris was in relation to their ship could help sailors navigate the waters, quickly and with ease.

To find the height of the star, sailors used the quadrant, the first latitude-measuring tool. For sailors, the quadrant was a simple tool made from wood or metal. Due to its simplicity, sailors learned quickly how to use the instrument. First, they would line the sights of the quadrant up with Polaris. Using the tool, they could measure the angle between the horizon and Polaris to determine their latitude. To do this, they looked at the recordings of the degrees along the arc of the tool. The quadrant remained one of the most common navigational tools used by sailors for a long time. It used a combination of astronomy and math to lead them successfully to the New World.

Based on the information in the article, what can be inferred about the inventors of the quadrant?

Answer from: Quest

in the short story the slip-over sweater by jesse stuart, the main character and narrator shan is friends with grace, an intelligent girl he has known since childhood and with whom he used to be in love.

at the beginning of the story, shan believes he’s no longer in love with grace, but loves jo-anne instead. in order to buy a slip-over sweater and have jo-anne wear it so that the other students would know she loved him too, shan takes a loan at the bank.

while jo-anne is wearing shan’s sweater, his friend grace starts to wear another popular boy’s one, roy’s sweater. because of that, the other students begin to pay attention to grace and compliment her perseverance and effort. they admire her for walking 5 miles to school every day, despite the weather, and still getting the best grades. shan, who knows all of that for a fact, says, as the narrator, ‘and i knew she had the durability and the toughness of a storm-battered mountain oak.’ he compares his friend’s strength – not only physical, but also of character – to an oak tree, whose wood is known for being sturdy.

as the story goes on, shan changes his behavior out of concern for the debt he has to pay at the bank. his new girlfriend jo-anne never asks him what is wrong nor offers any sort of . instead, she breaks up with shan for not being as fun as she thought he was supposed to be. grace, however, not only asks about shan’s problem, but him make the money he needs. shan can’t but notice how different the girls are and what a wonderful person grace is. even though he used to find jo-anne prettier at the beginning of the story, he now says, ‘grace was as beautiful as our mountain was in april, prettier than a blossom of wild phlox or a mountain daisy.’ his comparing grace to a mountain or something that exists on a mountain (such as a mountain oak or daisy) certainly has important meaning since shan loves the mountain and everything about it and he knows the mountain thoroughly. shan also loves and knows grace as completely as he does the mountain.
