Gemma is planning her vacation and has been hoping for several years to travel to Hawaii. She only has one week to visit, though, so she has to make the most of her trip. Her goal is to see as much as possible in a short period of time, while also giving herself a chance to relax and enjoy the experience.
Based on Gemma's preferences and limited time, which of the following travel guides will be best for her?
- A. Exploring the Hawaiian Islands: The Best Waterfalls on the Big Island and Maui
- B. Na Pali: The Two-Day Hike That Changes Everything
- C. Pineapples, Taro, and Roasted Pigs: A Dining Guide to Hawaii
- D. The Top Ten: Beaches, Restaurants, and Sightseeing in Honolulu and on Oahu
Correct Answer: A
Rationale: Given Gemma's goal of seeing as much as possible in a short time while enjoying outdoor activities and nature, the best travel guide for her would be 'Exploring the Hawaiian Islands: The Best Waterfalls on the Big Island and Maui.' This guide aligns with her interest in outdoor activities and waterfalls, making it the ideal choice to enhance her trip experience. Choice B, 'Na Pali: The Two-Day Hike That Changes Everything,' focuses on a specific hike and may not cover a broad range of attractions Gemma wants to explore. Choice C, 'Pineapples, Taro, and Roasted Pigs: A Dining Guide to Hawaii,' is more food-oriented and doesn't cater to Gemma's interest in outdoor activities. Choice D, 'The Top Ten: Beaches, Restaurants, and Sightseeing in Honolulu and on Oahu,' while offering a variety of attractions, doesn't specifically target Gemma's interest in exploring waterfalls and the natural beauty of Hawaii as she desires.

Magnesium is an important nutrient that supports immune system functioning and helps protect the body against cardiovascular diseases. Symptoms of magnesium deficiency rarely surface among populations in developed countries, but concern is growing that many people may not have sufficient body stores of this metal. Surveys show that most Americans do not receive a minimum daily requirement of magnesium in their diets.
Magnesium is absorbed from foods by the intestines, before the circulatory system transports it to the body's tissues. Less than one-half of ingested magnesium normally is taken up in this way.
Health issues affecting the digestive tract may impair magnesium absorbance. For example, gastrointestinal disorders such as Crohn's disease can limit magnesium uptake. The kidneys normally limit urinary excretion of magnesium, a function that can help make up for low dietary intake. However, alcohol abuse and certain medications can affect this balance and thereby lead to magnesium depletion.
Symptoms of magnesium deficiency include vomiting, fatigue, and loss of appetite. More severe cases can include symptoms such as muscular cramps, seizures, and coronary abnormalities.
Magnesium insufficiency also can affect the body's ability to absorb other cations, including calcium and potassium, and can lead to other health complications. Good sources of dietary magnesium include leafy green vegetables, potatoes, nuts, and seeds.
The word 'cation' is closest in meaning to:
- A. element
- B. nutrient similar to magnesium
- C. symptom of deficiency
- D. nutritional supplement
Correct Answer: A
Rationale: The word 'cation' refers to a positively charged ion, which is an atom or molecule that has lost one or more electrons. It is not related to nutrients, symptoms, or supplements. Therefore, the closest in meaning to 'cation' among the given choices is 'element.' In the provided extract, it mentions that cations like magnesium can affect the body's ability to absorb other cations, including calcium and potassium. This further emphasizes that 'cation' is related to elements rather than nutrients, symptoms, or supplements.
Harriet Tubman was a runaway slave from Maryland who became known as the "Moses of her people." Over the course of 10 years, and at great personal risk, she led hundreds of slaves to freedom along the Underground Railroad, a secret network of safe houses where runaway slaves could stay on their journey north to freedom. She later became a leader in the abolitionist movement, and during the Civil War she was a spy for the federal forces in South Carolina as well as a nurse.
Harriet Tubman's name at birth was Araminta Ross. She was one of 11 children of Harriet and Benjamin Ross born into slavery in Dorchester County, Maryland. As a child, Ross was "hired out" by her master as a nursemaid for a small baby. Ross had to stay awake all night so that the baby wouldn't cry and wake the mother. If Ross fell asleep, the baby's mother whipped her. From a very young age, Ross was determined to gain her freedom.
As a slave, Araminta Ross was scarred for life when she refused to help in the punishment of another young slave. A young man had gone to the store without permission, and when he returned, the overseer wanted to whip him. He asked Ross to help but she refused. When the young man started to run away, the overseer picked up a heavy iron weight and threw it at him. He missed the young man and hit Ross instead. The weight nearly crushed her skull and left a deep scar. She was unconscious for days, and suffered from seizures for the rest of her life.
In 1844, Ross married a free black named John Tubman and took his last name. She also changed her first name, taking her mother's name, Harriet. In 1849, worried that she and the other slaves on the plantation were going to be sold, Tubman decided to run away. Her husband refused to go with her, so she set out with her two brothers, and followed the North Star in the sky to guide her north to freedom. Her brothers became frightened and turned back, but she continued on and reached Philadelphia. There she found work as a household servant and saved her money so she could return to help others escape.
This passage is mainly about
- A. slaves in the Civil War.
- B. how slaves escaped along the Underground Railroad.
- C. Harriet Tubman's role as an abolitionist leader.
- D. Harriet Tubman's life as a slave.
Correct Answer: C
Rationale: The passage is mainly about Harriet Tubman's role as an abolitionist leader. It discusses her efforts to help slaves escape to freedom through the Underground Railroad and highlights her significant impact on the abolitionist movement. The focus is on Tubman's leadership and involvement in the fight against slavery, rather than just her life as a slave or the general experience of slaves during the Civil War. Choices A, B, and D are incorrect because while the passage mentions slavery, the Civil War, and Tubman's life as a slave, the primary emphasis is on her leadership and activism in the abolitionist movement.
