11. Which of the following statements best summarises the main idea of this paragraph?

Question

BlackTom AI · Accepted Answer

Developments in technology have been improving healthcare. This one-line summary captures the paragraph’s general claim and fits the scope of a main idea.

1. Relevant knowledge points and concepts
- Main idea (topic sentence): the central, overarching claim the paragraph supports.
- Supporting details vs. main idea: examples, devices, or consequences illustrate the main idea but do not replace it.
- Precision and scope: the best main-idea choice must be general enough to encompass supporting details and accurate in meaning.

2. Step-by-step reasoning
- Identify the paragraph’s focus: it centers on technological change and its effects on healthcare.
- Compare each option’s scope with that focus:
  a) Mentions “developing healthy technology makes us feel better” — this is narrow (emotional effect) and awkwardly phrased; unlikely to be the paragraph’s central claim.
  b) States broadly that “Developments in technology have been improving healthcare” — a general, clear assertion that can encompass many supporting examples (devices, procedures, access).
  c) Claims “Healthcare devices have developed significantly recently” — narrower (devices only) and adds a specific time frame (“recently”) not necessarily in the paragraph.
  d) Says “Technological developments make global patients more efficient” — illogical focus on patients’ efficiency and worded oddly; not a typical main idea.

3. Calculations
- None required.

4. Why the correct answer is correct
- Option b is general, grammatically clear, and accurately summarizes a paragraph whose examples and details describe how technology has improved diagnosis, treatment, access, or outcomes. It functions as the umbrella claim that supporting sentences would illustrate.

5. Why the other options are incorrect
- a: Too specific and vague in meaning (“feel better”) and doesn’t capture systemic healthcare improvement.
- c: Restricts the claim to “devices” and “recently,” narrowing the scope of the paragraph.
- d: Unclear and implausible focus on making “global patients more efficient,” which misstates typical healthcare benefits.

6. Conclusion
Option b is the best summary and matches the provided correct answer: b. Developments in technology have been improving healthcare.
