Because gold is a soft metal, it is sometimes combined with another metal to harden it, such as copper.

Which of the following is the purpose of the passage above?

B. To recommend

C. To inform

D. To analyze

Answer Explanation:

The passage provides information about the characteristics and composition of gold, including its purity levels and the reason for using alloys like 14-carat gold.

Q #1: "The Santa Barbara journal: Exciting news today from Vandenberg Space Force Base as it has ended its Delta V Heavy rocket program to make way for the new Atlas V program. Riddled with difficulties, Delta V Heavy saw only moderate success throughout its 21-year history. Developed on the heels of the last tragic Space Shuttle flight, expectations for the Delta V Heavy have far exceeded its reality, Future hopes now live with the Atlas V program developed by Lockheed Martin. A social media post: @ggh723 The space program is an outdated use of taxpayer funds. We have enough problems on earth to worry about what's happening in the universe. Which of the following is evidence that supports the claim in the social media post?

C. $1.5 billion was budgeted last year for social programs, while $10 million went to the space program.

D. The federal government's spending on the space program outpaces its contribution to education in the United States.

Answer Explanation

This evidence suggests a comparison between the spending on the space program and education, implying that there may be an imbalance in allocation of funds, which could support the argument that the space program is an outdated or misdirected use of taxpayer funds.
Q #2: What is all this talk of cicadas lately in the United States? You might be wondering why the media has featured it, but in fact, the discussion about cicadas has emerged about as predictably as the cicadas themselves from their underground refuge. Let's get oriented with some background on cicadas. What is a cicada? A typical definition will at least tell you that the cicada is a large, loud insect with long transparent wings, mostly found in warm countries. A more detailed response might also inform you that cicadas have short antennae and wide-set eyes that jut out, with delicate, translucent wings and that not only is the cicada loud, but few creatures make a louder sound. In fact, it is male cicadas that are the noisy ones, to the tune of 80 to 100 decibels, which is like the roar of a loud engine. This is because male cicadas make a strident, high buzzing by vibrating two membranes on its abdomen called tymbals, effectively turning its body into a kind of echo chamber or drum, Female cicadas cannot replicate the buzzing, though they respond with a clicking sound when they are ready to mate. Although there are several species of cicada, mating typically takes place in trees whereafter the female deposits the eggs into the bark. Wher the eggs hatch, the larval cicadas, called nymphs, drop to the ground and burrow. They then live as nymphs for most of their lives over 6 feet underground, with both male and female cicadas dying within weeks of their emergence from the soil. This is particularly true for North American cicadas, especially the Magicicodo, or periodical cicadas, which regularly emerge in intervals of 13 or 17 years, depending on the species and the location. This is why talk of cicadas in the media is as predictable as their emergence in the US. Which of the following is the most likely reason male cicadas make a buzzing sound?

A. To attract a mate

B. To locate food sources

C. To orient via echolocation

D. To ward off predators

Answer Explanation

The passage states that male cicadas make a strident, high buzzing sound to attract female cicadas when they are ready to mate. This indicates that the buzzing serves as a mating call to attract potential mates.
Q #3: I sit on the headlands of Neah Bay, Washington, and watch a mother humpback and her calf slip through the icy Pacific waters. I recognize this whale by her distinctive tail pattern, as unique to this humpback as my fingerprints are to me. Once, heavy hunting using harpoons extirpated the species from the region, and only a ban on whaling allowed populations of humpbacks to recover As this gray female rises to the surface, she exhales, sending up a spout nearly 20 feet high. She rolls on her side and lifts her scalloped-edge flipper in salute, then slaps it on the water. I adjust my lens and take my shot. This is the only type of whale hunting i find acceptable-hunting with a camera. Which of the following statements conveys the main idea of the passage?

A. Humpback whale populations are finally recovering after nearly being wiped out.

B. This particular humpback whale has never been seen previously by the author

C. Humpback whales travel in waters near Washington.
