1. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?

A. Human papillomavirus (HPV)
B. Chlamydia
C. Gonorrhea
D. Syphilis

Correct answer: B

Rationale: Chlamydia is the correct answer because if left untreated, it can lead to serious complications such as pelvic inflammatory disease (PID) in women and epididymitis in men, both of which can cause infertility. Chlamydia is a common sexually transmitted infection that often presents with no symptoms, making it important for individuals to get tested regularly, especially if they are sexually active. It is crucial to detect and treat Chlamydia early to prevent long-term consequences such as infertility. Human papillomavirus (HPV) can lead to genital warts and certain types of cancer but is not typically associated with infertility. Gonorrhea and syphilis can cause serious health problems if untreated, but infertility is more commonly associated with Chlamydia.

2. Based on the pattern in the headings, which of the following is a reasonable heading to insert in the blank spot?

A. Gray Tree Frog
B. Tropical Frogs
C. Newts
D. Spadefoot Toads

Correct answer: A

Rationale: By observing the headings provided in the extract, we can see that they are sorted alphabetically starting from 'Gray Tree Frog.' Following this alphabetical order, the next heading to be inserted in the blank spot would also come alphabetically next, which is 'Gray Tree Frog.' Choices B, C, and D do not follow the alphabetical pattern established by the existing headings and are therefore incorrect.

3. How does the stability of an atom's nucleus influence its radioactive decay?

A. Stable nuclei never undergo radioactive decay.
B. Unstable nuclei are more likely to decay through various processes.
C. Decay releases energy, making stable nuclei more prone to it.
D. The element's position on the periodic table determines its decay rate.

Correct answer: B

Rationale: Unstable nuclei are more likely to decay through various processes. The stability of an atom's nucleus is a crucial factor in determining whether it will undergo radioactive decay. Unstable nuclei have an excess of either protons or neutrons, causing an imbalance in the nucleus. To achieve a more stable configuration, these nuclei will undergo radioactive decay by emitting particles or energy. On the contrary, stable nuclei are less likely to undergo radioactive decay as they possess a balanced number of protons and neutrons. Choice A is incorrect because stable nuclei can still undergo radioactive decay, albeit less frequently. Choice C is incorrect as decay does not make stable nuclei more prone to it; rather, it stabilizes them. Choice D is incorrect because an element's decay rate is primarily determined by the nucleus's stability, not its position on the periodic table.

4. What is the author’s likely purpose in writing this passage about Queen Victoria?

A. To persuade the reader to appreciate the accomplishments of Queen Victoria, especially when placed against the failures of her forebears.
B. To introduce the historical impact of the Victorian Era by introducing to readers the queen who gave that era its name.
C. To explain how small events in history placed an unlikely princess in line to become the queen of England.
D. To indicate the role that King George III’s many sons played in changing the history of England.

Correct answer: C

Rationale: The correct answer is C. The author's purpose in writing this passage is to explain how small events in history led to an unlikely princess, Princess Alexandrina Victoria, becoming the queen of England. The passage discusses the family background of Queen Victoria and how a series of events, including the lack of legitimate heirs from King George III's sons, ultimately paved the way for her ascension to the throne. Choice A is incorrect because the passage is more focused on presenting historical events rather than persuading readers to appreciate Queen Victoria's accomplishments. Choice B is also incorrect as the passage does mention the Victorian Era but is primarily centered around Queen Victoria's personal journey to the throne. Choice D is incorrect as the passage does briefly mention King George III's sons, but it does not primarily focus on their role in changing the history of England.

5. Which of the following is a function of the liver?

A. Producing digestive enzymes
B. Storing bile
C. Filtering waste products from the blood
D. Transporting nutrients to cells

Correct answer: B

Rationale: The correct function of the liver is to store bile. Bile is produced in the liver and stored in the gallbladder until it is needed to aid in the digestion of fats. While the liver does produce bile, its primary role is to store and release it. Choices A, C, and D are incorrect. Producing digestive enzymes is mainly the function of the pancreas, filtering waste products from the blood is primarily done by the kidneys, and transporting nutrients to cells is typically associated with the circulatory system rather than the liver.
