Which sentence is correct?

Correct Answer: A

Rationale: A prescription is a written order from a physician or other licensed health practitioner for the preparation and administration of a medication. In this context, 'prescription' is the correct term for the document written by a physician to authorize the dispensing of medication. The other options (B, C, D) use incorrect terms such as 'recommendation,' 'report,' and 'subscription,' which do not accurately convey the action of a physician prescribing medication. Therefore, choice A is the correct answer as it accurately describes the action taken by the physician.

Correct Answer: C

Rationale: The word 'environment' refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It encompasses the elements both inside and outside of an individual, including physical, biological, social, and cultural factors. Option C, which mentions the elements inside and outside of a person, is the most accurate description of the word 'environment.' Choices A, B, and D do not capture the comprehensive nature of the term 'environment' and are therefore incorrect.

Correct Answer: B

Rationale: The correct answer is B: 'Incurable.' Incorrigible refers to something or someone that is beyond correction or incurable. It implies a persistent behavior or trait that is difficult or impossible to change. Choice A, 'Curable,' is incorrect because incorrigible means the opposite - not capable of being cured. Choice C, 'Treatable,' is incorrect because incorrigible implies a condition that is resistant to treatment. Choice D, 'Temporary,' is incorrect as incorrigible suggests a long-lasting or permanent state, not something temporary.

Correct Answer: D

Rationale: The correct answer is 'D: Sunken.' Concave refers to a surface or shape that curves inward, while 'sunken' is the closest synonym, also indicating something that is depressed or hollowed inward. Choice 'B: Convex' is incorrect as it is the opposite of concave, representing a shape that bulges outward. Choices 'A: Sunburned' and 'C: Puffed out' do not relate to the concept of concave shapes.

Correct Answer: B

Rationale: When a patient's condition is deteriorating, it means they are getting worse. This indicates a decline or worsening in their health status, requiring immediate attention or intervention. Choice A is incorrect because 'improving' means the opposite of deteriorating. Choice C is incorrect as 'stable' means there is no significant change. Choice D is incorrect as 'recovering' means getting better, which is the opposite of deteriorating.

Correct Answer: B

Rationale: The correct answer is B: 'envelope.' The mail carrier typically delivers envelopes containing mail to every mailbox on the block. Envelopes are commonly used to protect and contain letters, making them the most suitable choice in this context. Choices A, C, and D are incorrect because while the mail carrier may deliver letters, packages, or documents, the most common item placed in mailboxes is an envelope containing mail.

Correct Answer: A

Rationale: The correct answer is A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.

Correct Answer: B

Rationale: The term 'External' refers to something that is located outside the body. In this context, it specifically denotes a position or location that is beyond the confines of the body's boundaries. Choice A is incorrect as 'External' means outside, not inside. Choice C is incorrect as it confuses the internal exposure with external positioning. Choice D is incorrect as 'External' does not necessarily mean near the skin, but rather outside the body.

Correct Answer: D

Rationale: The sentence 'The spy had to snake his way onto the train' correctly uses 'snake' as a verb. In this context, 'snake' is used to describe the spy's action of moving cunningly and stealthily, similar to how a snake slithers, making it the appropriate choice where 'snake' functions as a verb. The other choices use 'snake' as a noun to refer to the reptile itself or its movement, not as a verb.
