1. Which of the following words is an example of a conjunction?

• A. Quickly
• B. But
• C. Very
• D. Apple

Correct answer: B

Rationale: The correct answer is "But". A conjunction is a word that connects words, phrases, or clauses. In this case, "But" is a conjunction used to indicate a contrast or opposition between ideas. The other choices, "Quickly", "Very", and "Apple", are not conjunctions. "Quickly" is an adverb, "Very" is an adverb, and "Apple" is a noun, none of which serve the function of connecting words, phrases, or clauses as conjunctions do.

2. Scoliosis is a condition characterized by abnormal lateral curvature of the spine. Which part of the spine is most commonly affected?

• A. Cervical spine (neck)
• B. Thoracic spine (upper back)
• C. Lumbar spine (lower back)
• D. All of the above

Correct answer: B

Rationale: Scoliosis most commonly affects the thoracic spine, which is the upper back region. While scoliosis can potentially affect any part of the spine, the thoracic spine is the most frequently involved area. This region is more commonly affected due to the natural structural curves of the spine and the biomechanics of the thoracic area. The cervical spine (neck) and lumbar spine (lower back) can also be affected by scoliosis, but the thoracic spine is the primary area of involvement in most cases. Therefore, the correct answer is B, as it is the part of the spine most commonly affected by scoliosis.

3. What is the net ionic equation for the reaction: 2HCl(aq) + Ba(OH)2(aq) → 2H2O(l) + BaCl2(aq)?

• A. 2H+(aq) + 2OH-(aq) → 2H2O(l)
• B. 2HCl(aq) + Ba(OH)2(aq) → BaCl2(aq) + 2H2O(l)
• C. 2H+(aq) + Ba2+(aq) → Ba2+(aq) + 2H+(aq)
• D. Ba(OH)2(aq) + HCl(aq) → BaCl2(aq) + 2H2O(l)

Correct answer: A

Rationale: In the given reaction, the complete ionic equation is: 2H+(aq) + 2Cl-(aq) + Ba2+(aq) + 2OH-(aq) → 2H2O(l) + Ba2+(aq) + 2Cl-(aq). Spectator ions (Ba2+ and Cl-) do not participate in the net ionic equation, which simplifies to: 2H+(aq) + 2OH-(aq) → 2H2O(l). This equation represents the significant species involved in the reaction, showcasing the formation of water from the combination of hydrogen ions and hydroxide ions, resulting in the production of water molecules.

4. The first midwife uses 2/5 of her monthly contribution to pay for rent and utilities. She saves half of the remainder for incidental expenditures, and uses the rest of the money to purchase medical supplies. How much money does she spend on medical supplies each month?

• A. $600
• B. $800
• C. $1,000
• D. $1,200

Correct answer: A

Rationale: The first midwife contributes $2000. She spends $800 on rent and utilities. After paying for rent and utilities, $1200 remains. Half of this amount, which is $600, is saved for incidental expenditures. Therefore, the first midwife spends the remaining $600 on purchasing medical supplies each month. Choice A, $600, is the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the amount spent on medical supplies as calculated in the given scenario.

5. Select the correct definition of the underlined word having multiple meanings in the sentence: 'Natalie’s fingers were calloused after practicing her bass.'

• A. Kind of fish
• B. Low and deep sound
• C. Lowest male singing voice
• D. A guitar with four strings that makes low sounds

Correct answer: D

Rationale: In this sentence, 'bass' refers to a guitar with four strings that makes low sounds. The context of Natalie practicing suggests that it is referring to a musical instrument, specifically the bass guitar, rather than a fish, sound, or voice. Therefore, the correct answer is D. Choice A, 'Kind of fish,' is incorrect as the sentence context does not relate to fish. Choice B, 'Low and deep sound,' is incorrect because the sentence refers to practicing an instrument, not just a sound. Choice C, 'Lowest male singing voice,' is also incorrect as the sentence context is not related to singing but to playing an instrument.
