1. Which type of radiation involves the emission of helium ions?

• A. Beta
• B. Alpha
• C. Gamma
• D. Delta

Correct answer: B

Rationale: Alpha radiation involves the emission of helium ions. Helium ions are composed of two protons and two neutrons, which is the same as the nucleus of a helium atom. This type of radiation has low penetration power and can be stopped by a piece of paper or human skin, making it less harmful compared to other forms of radiation like beta or gamma radiation. Beta radiation involves the emission of high-speed electrons, while gamma radiation involves electromagnetic waves with high energy. Delta radiation is not a recognized form of radiation in this context, making it an incorrect choice.

2. Why are bacteria and blue-green algae often classified together?

• A. Both are gymnosperms.
• B. Both are prokaryotes.
• C. Both are autotrophs.
• D. Both are pathogens.

Correct answer: B

Rationale: Bacteria and blue-green algae (cyanobacteria) are often classified together because they are both prokaryotes. Prokaryotes are unicellular organisms that lack a membrane-bound nucleus and other membrane-bound organelles. This characteristic distinguishes them from eukaryotic organisms, which have these membrane-bound structures. Choice A is incorrect because gymnosperms are seed-producing plants with naked seeds, not bacteria or blue-green algae. Choice C is incorrect because being an autotroph (able to produce its own food) is not a reason for classifying them together. Choice D is incorrect because not all bacteria and blue-green algae are pathogens; many of them are beneficial or neutral to other organisms.

3. Which word in the following sentence functions as the direct object: 'The nurse helped the patient with the medication'?

• A. helped
• B. nurse
• C. patient
• D. medication

Correct answer: C

Rationale: In the sentence 'The nurse helped the patient with the medication,' the direct object is 'patient' because it receives the action of being helped. The direct object typically answers the question 'whom' or 'what' after the verb. In this case, 'the patient' is the one being helped by the nurse, making it the direct object. Choices A, B, and D are incorrect. 'Helped' is the verb, 'nurse' is the subject performing the action, and 'medication' is part of a prepositional phrase and does not directly receive the action of the verb.

4. If a doctor has an EXEMPLARY record, her work is ______

• A. Ordinary
• B. Praiseworthy
• C. Disappointing
• D. Confusing

Correct answer: B

Rationale: An exemplary record signifies work that is praiseworthy, exceptional, or outstanding. Therefore, the correct answer is 'B: Praiseworthy.' Choices 'A: Ordinary,' 'C: Disappointing,' and 'D: Confusing' do not align with the meaning of having an exemplary record and are thus incorrect.

5. What is the main idea of the passage?

• A. Bicycles have become a common mode of transportation worldwide.
• B. The first modern bicycle was invented in 1818 in Germany.
• C. Innovations and improvements in bicycle design have made bicycles popular for recreation and transportation globally.
• D. Bicycles are now built, used, and enjoyed globally.

Correct answer: C

Rationale: The main idea of the passage is that innovations and improvements in bicycle design have made bicycles one of the most popular means of recreation and transportation worldwide. The passage outlines the evolution of bicycles from their early designs to the modern versions, emphasizing how these changes have contributed to their popularity. Choice A is incorrect because it focuses only on the current status of bicycles, while the main idea encompasses the evolution and improvements in design. Choice B is incorrect as it mentions the invention of the first modern bicycle but does not address the overall impact of innovations on bicycle popularity. Choice D is incorrect as it simply states a fact without capturing the essence of the passage, which is about the impact of design improvements.
