Mars, an orange-red planet often visible in the night sky, has long been studied by humans. In the past, scientists used telescopes to chart the movements of Mars. Modern scientists study the planet in more detail using tools and instruments in addition to telescopes. NASA has a Mars Exploration Program to try to understand whether Mars was, is, or can be, a habitable world.

Which is NOT an accurate quote from this passage?

Young Enterprise Services

Young Enterprise Services (YES) is a program created to encourage entrepreneurship in 14- to 18-year-olds who have already shown a clear ability for starting businesses. The program, which began in 2002, has provided loans, grants, and counseling—in the form of workshops and individual meetings with entrepreneurs—to over 7500 young people. The future of YES, however, is now at risk.

One complaint is that the funds that YES distributes have disproportionately gone to young people from low-income families. Though no one has claimed that any of the recipients of YES funds have been undeserving, several families have brought lawsuits claiming that their funding requests were rejected because of the families’ high levels of income. 

Another challenge has been making sure that a young person, not his or her family, is receiving the funding. The rules state that the youth must create the business plan and that any profits above $1,000 be placed in a bank account. The rules say that the money can only be used for education, investment in the business, and little else. There have been cases of parents or even a neighbor using the money for their business.

On the other hand, YES has had some real success stories. A 14-year-old girl in Texas used the knowledge and funding she received through the program to connect with a distributor who now carries her line of custom-designed cell phone covers. Two brothers in Alaska have developed an online travel service for young people vacationing with their families. Both of these businesses are doing well and earning money. Unfortunately, these and other successes have received little media coverage. This is a shame, but one that can be fixed.

Which piece(s) of text evidence describes a challenge that YES has encountered?

Ancient Paintings

Archaeologists working in two recently discovered limestone caves in Sarawak, Malaysia, have found a collection of 51 paintings estimated to be 6,000 to 12,000 years old. The images are unusual in their medium, manner of display, and subject matter. These are not merely wall or ceiling paintings. Stones—some as small as notebooks, some as large as doors—have been chipped and otherwise shaped to form rough canvases for painted individual works. 

Some of the pieces are stacked, while others are arranged upright in an overlapping pattern so that one can “flip through” the smaller pieces in the collection with relative ease. Hunters, warriors, and hunted animals, the typical cave art subjects, are mostly absent from these works. Instead, domestic scenes are represented, including food preparations, family meals, and recreational activities.

Though no tools have been found in the area, the lines’ fineness suggests the use of sophisticated animal-hair brushes. Gypsum, manganese, malachite, and other minerals were painstakingly ground and mixed with binding materials such as vegetable and animal oils to form the paints. One probable reason for the high level of artistry is that the paintings may have been produced in the open air, where the light was good, and then brought into the cave.

However, it is the purpose of the paintings that is the most curious. Most interestingly, it may be that the collection represents a sort of family tree. Many paintings appear to feature some of the same people, and it is tempting to think of these works as family portraits. Indeed, one figure, seen as a child with a mark on its forehead—the stone has been chipped away to represent the mark—is shown in other paintings as both a young person and an adult with the same mark.

Which piece of text evidence from the passage would best convey that the Malaysian painters were skilled artists?

Inventions

Every day it seems, new inventions surface that promise to add value to our day-to-day lives. But did you know, many of the inventions we interact with daily were developed entirely by accident? 

Take the microwave, for instance. This accidental invention was developed by engineer Percy Spencer who, upon experimenting with a microwave-emitting magnetron, found that the candy bar in his pocket had begun to melt. Spencer was then able to harness this radiation into the microwave we use today to make snack time a speedy process!

Perhaps one of today’s most well-known accidental inventions, the potato chip, was born when a customer kept requesting that his french fries be sliced thinner and made crispier. Though chef George Crum responded with the chips as a joke, they quickly became a favorite snack worldwide! 

Even the match is a result of accidental invention. When pharmacist John Walker was stirring chemicals, he noticed that the end of his stirring stick had dried into a hardened lump. When attempting to scrape the dried residue off, a flame sparked, and so did Walker’s idea to turn this accident into a helpful tool!

So, the next time your science experiment doesn’t go as planned, or you burn what you have cooked on the stove, keep in mind that some of today’s most valued inventions were discovered when the inventor least expected it!

According to the passage, who invented the potato chip?

Adapted from Aesop’s The Ants & the Grasshopper (620-560 BCE)

One bright day in late autumn, a family of Ants were bustling about in the warm sunshine, drying out the grain they had stored up during the summer, when a starving Grasshopper, his fiddle under his arm, came up and humbly begged for a bite to eat.

"What!" cried the Ants in surprise, "haven't you stored anything away for the winter? What in the world were you doing all last summer?"

"I didn't have time to store up any food," whined the Grasshopper; "I was so busy making music that before I knew it, the summer was gone."

The Ants shrugged their shoulders in disgust.

"Making music, were you?" they cried. "Very well; now dance!" And they turned their backs on the Grasshopper and went on with their work.

Which piece of text evidence supports the following claim?

Grasshopper is lazy and irresponsible.
