- A. Blocking
- B. Hindering

- A. To a
- B. Very strong

Correct answer: D
Rationale: The correct answer is D. The phrase 'Went form' contains a typographical error. It should be 'went from' to indicate the change in condition correctly.

- A. Harmless
- B. Entering into a body part

Correct answer: B
Rationale: The correct answer is 'B: Entering into a body part.' 'Invasive' refers to something that invades or penetrates into a body part. Choice A, 'Harmless,' is incorrect as invasive implies a negative impact. Choice C, 'Mildly irritating,' is incorrect as invasive implies a more serious intrusion. Choice D, 'Non-penetrative,' is incorrect as invasive specifically denotes penetration or entry.
4. What does 'abrupt' mean?
- A. Gradual
- B. Sudden
- C. Delayed

- A. Blood pressure

Rationale: In the context provided, 'dilation' refers to the widening or opening of the cervix during labor as the woman progresses towards childbirth. Choice A, 'Blood pressure,' is incorrect as dilation does not relate to blood pressure. Choice C, 'Birth process,' is too broad and does not specifically define the term 'dilation.' Choice D, 'Exhumation,' is unrelated and does not fit the context of the sentence.
