Jazmin has written this essay for her science class. Read Jazmin’s
essay and look for any corrections that she needs to make. When
you finish reading, answer the questions that follow.

(1) Humans are naturally curious beings. (2) We are driven
to search for new places to explore. (3) Given how many natural
wonders have been discovered around the world, isn’t it amazing that
there are still natural wonders to find? (4) In the year 2000, two
miners in Mexico stumbled upon one such surprise—a cave of crystals
unlike any other.

(5) Nine hundred and eighty feet below the surface of Naica,
Mexico, miners were excavating a new tunnel and found a cave filled
with giant crystals. (6) The cave is a geological wonder because it
contains some of the largest natural crystals ever discovered in the
world. (7) Scientists and explorers studying the cave named it Cave
of Crystals—for the surprises inside. (8) These crystals are Classified
as selenite crystals, meaning they are translucent. (9) Most are
between 20 and 36 feet long and weigh around 55 tons.

(10) At first, scientists wondered how the crystals grew so large
inside the cave. (11) Naica is on top of an ancient underground fault,
which is a break in the ground where the tektonic plates of Earth
have shifted. (12) Below the cave is a magma chamber filled with
lava. (13) Over time, the cave was flooded with groundwater that
trickled in from the surface. (14) With the water inside the cave and
the heat from the magma chamber, the cave remained a consistent
temperature for 500,000 years, and this created the perfect
environment to grow crystals.

(15) Scientists don’t know much about the crystals yet; the
extreme conditions inside the Cave of Crystals make it dangerous
to stay inside the cave for more than a few minutes at a time.
(16) Because the magma chamber is right below the cave, the
temperature is between 100°F and 150°F. (17) The relative humidity
inside the cave is between 90% and 100%. (18) The average
humidity in Mexico City is about 50%, making the cave’s humidity
almost double the average of the nation’s capital. (19) In order to
learn more about this impressive minerallogical discovery, scientists
exploring the caves are working to develop strategies and tools that
will help them stay underground longer.

(20) Amazing discoveries like the Cave of Crystals in Mexico
help us learn more about our world and its natural wonders.
(21) If there is a shocking cave like this 980 feet below the surface
of Mexico. (22) Then there could be more discoveries just like it in
other parts of the world. (23) There are still corners of the world that
have not been seen by human eyes, perhaps with surprises just as
dazzeling as the Cave of Crystals.

A Pet Like No Other
Read the selection and choose the best answer to each question. Then fill in the answer on your answer document. Shannon has written this essay to share an experience with her classmates. Read Shannon’s essay and look for any corrections that she needs to make. When you finish reading, answer the questions that follow.

A Pet like No Other

(1) Adopting a pet can be a great experience. (2) A pet can teach children responsability and encourage families to spend time together. (3) Household pets hold a special place in the hearts of their owners, but there are other types of animals that also need care and attention from humans—endangered and threatened animals. (4) Although they may be a continent away, it is possible to “adopt” these animals.

(5) Adopting a tiger, polar bear, or sea turtle is very different than visiting an animal shelter to physically adopt and bring home a pet. (6) When someone adopts an endangered or threatened animal through the World Animal Foundation (WAF), it is a symbolic adoption. (7) The WAF is a volunteer organization whose mission is to provide protection and support for animals all over the world. (8) Adopting one of their endangered or threatened animals is just one of the ways that people can show their love and concern.

(9) When I learned about the existence of WAF I asked my mother and father if I could support my favorite animal—the elephant. (10) My parents agreed that it was an incredible idea for an important cause, so we began the formal adoption process. (11) The volunteers who work at WAF make the process of adopting animals easy and pleasant. (12) Prospective adoptive parents can learn about mammals, reptiles, birds, fish, bugs, and even farm animals as they select which species they want to adopt online. (13) As he watched me go through the process, my little brother also became interested in WAF, and he selected a crab—his favorite animal. (14) We were incredibly proud of our symbolic adoptions. (15) When people donate to the WAF and adopt an animal, they help the organization build sanctuaries for injured animals, protect the habitats of endangered animals, and create educational programs. (16) We hope that by adopting through the organization, we can help animals live longer, healthier lives and also preserve endangered species.

(17) Although our new pets will remain in the wild, we received packets of information about these amazing creatures. (18) WAF sends photographs, an Adoption Certificate, cards containing fun facts, and maps depicting the animals’ habitats. (19) The best part was that after my brother and I received the package, we showed our photographs and information cards to our friends and family. (20) Some of my nieces, nephews, and cousins now plan to adopt animals of their own.

(21) While any pet can positively affect the life of its owner, adopting endangered or threatened animals is a unique experience. (22) Dogs, cats, and other animals that live in shelters certainly make great pets, but symbolic adoption provides direct help to rare animals such as an emperor penguin or a rhinoceros. (23) The mission of the World Animal Foundation is to educate others about animals around the globe while directly contributing to rescue and protection programs, I support their efforts. Third party trademark World Animal Foundation© was used in these testing materials.
