1. Which of the following distinguishes the isotopes of an element?

• A. Isotopes are atoms of the same element that have different ionic charges.
• B. Isotopes are atoms of elements within the same group on the periodic table.
• C. Isotopes are atoms of the same element that have different numbers of neutrons.
• D. Isotopes are atoms of the same element with different electron configurations.

Correct answer: C

Rationale: Isotopes are defined as atoms of the same element that have the same number of protons in their nucleus but different numbers of neutrons. This leads to variations in atomic mass for isotopes of an element. The different number of neutrons in isotopes results in differences in their atomic mass and properties while still belonging to the same element. Choice A is incorrect because isotopes do not have different ionic charges, they have the same chemical properties. Choice B is incorrect because isotopes are not atoms of elements within the same group on the periodic table; they are variants of the same element. Choice D is incorrect because isotopes of an element have the same electron configuration, differing only in the number of neutrons in the nucleus.

2. What key idea is conveyed in Frost's poem?

• A. Exploration of love and loss.
• B. Illustration of challenging life decisions.
• C. Reflection on life's journey and choices.
• D. Emphasis on the significance of choosing uncommon paths.

Correct answer: D

Rationale: The correct answer is D. Frost's poem emphasizes that opting for less conventional paths in life adds depth and meaning. Choices A, B, and C are incorrect because the poem specifically focuses on the importance of selecting uncommon routes rather than love, loss, general life decisions, or life's journey.

3. What is the network of vessels and ducts responsible for draining excess fluid and waste products from tissues?

• A. Circulatory system
• B. Digestive system
• C. Lymphatic system
• D. Respiratory system

Correct answer: C

Rationale: The correct answer is the Lymphatic system (option C). The lymphatic system is responsible for draining excess fluid and waste products from tissues. It works alongside the circulatory system to maintain fluid balance in the body. The circulatory system (option A) transports blood, the digestive system (option B) processes food, absorbs nutrients, and eliminates solid waste, while the respiratory system (option D) is responsible for gas exchange, specifically the intake of oxygen and removal of carbon dioxide.

4. Hampton was born and raised in Maywood, a suburb of Chicago, Illinois, in 1948. Which revision best improves the sentence?

• A. NO CHANGE
• B. in Maywood, of Chicago, Illinois in 1948.
• C. in Maywood, of Chicago, Illinois, in 1948.
• D. in Chicago, Illinois of Maywood in 1948.

Correct answer: C

Rationale: The corrected choice C 'in Maywood, of Chicago, Illinois, in 1948.' is the best revision as it places commas around the city and state, as well as around the year, improving clarity and readability. Choice A is incorrect as it does not provide the necessary punctuation for clarity. Choice B incorrectly places 'of Chicago' between 'Maywood' and 'Illinois,' disrupting the flow of information. Choice D reverses the order of 'Chicago, Illinois' and 'Maywood,' making it structurally incorrect.

5. How did Hedy Lamarr contribute significantly to the advancement of technology?

• A. The technology of the era wasn't advanced enough to easily implement Lamarr's system
• B. She collaborated with the science engineering team employed by Howard Hughes, the aviation tycoon
• C. She had several failed inventions, such as an improved traffic light and a carbonated drink
• D. Her work led to the future development of cellular phones, Bluetooth, and Wi-Fi.

Correct answer: D

Rationale: The correct answer is D because Hedy Lamarr's invention of a frequency-hopping system, along with George Antheil, laid the foundation for technologies like cellular phones, Bluetooth, and Wi-Fi. This significant contribution revolutionized communication technology. Choice A is incorrect because it focuses on the limitations of the era's technology rather than Lamarr's contributions. Choice B is incorrect as it briefly mentions her collaboration but does not directly relate it to technological advancements. Choice C is incorrect as it highlights her failed inventions, which are not indicative of her significant contributions to technology.
