Correct Answer: D

Rationale: The word 'ruminate' means to think deeply about something before making a decision. It specifically implies reflecting or pondering carefully on a matter, indicating a thoughtful consideration process. Choices A, B, and C are incorrect. 'Imply' means to suggest indirectly, 'transgress' means to go beyond limits or boundaries, and 'allay' means to diminish or put to rest feelings of fear or suspicion. These words do not convey the concept of thoughtful contemplation before making a decision.

Correct Answer: A

Rationale: The correct answer is A: 'patient.' The correct spelling should be 'patient.' 'Physician,' 'sodium,' and 'recommended' are all spelled correctly. 'Physician' refers to a medical doctor, 'sodium' is a chemical element, and 'recommended' is the past tense of the verb 'recommend.' Therefore, the misspelled word in the sentence is 'patient.'

Correct Answer: B

Rationale: The correct answer is B: Fontanel. Fontanels are spaces between the bones of a newborn's skull that allow for brain growth and development. The term 'fistula' (choice A) refers to an abnormal passageway between two organs or between an organ and the body surface, not related to newborn soft spots. 'Follicle' (choice C) is a structure in the skin that contains the hair root, not related to the skull. 'Fissure' (choice D) refers to a narrow opening or crack, which is not the term used for the soft spots on a newborn's head.

Correct Answer: B

Rationale: The correct answer is B: 'Straightforward.' Guileless means innocent, sincere, and without deceit. It describes someone who is honest and straightforward in their actions and speech. Choices A, C, and D are incorrect. 'Deceptive' means misleading or dishonest, 'Complex' means having many intricate parts, and 'Untrustworthy' means not reliable or trustworthy, all of which are opposite in meaning to guileless.

Correct Answer: B

Rationale: The correct answer is B: 'To begin or put into practice.' 'Initiate' means to start or commence something. Choice A, 'To finish,' is incorrect because 'Initiate' refers to the beginning of something, not its conclusion. Choice C, 'To delay,' is incorrect as it is the opposite of what 'Initiate' means. Choice D, 'To stop completely,' is also incorrect as it is the opposite of starting or initiating something.
