Question

read the following paragraph from the introduction paragraphs 1 - 3. people with covid - 19 who appear to be healthy can still spread the disease. a new artificial intelligence (ai) might be able to help. ai is a type of computer software that uses algorithms, or a series of instructions in code, to teach a machine to spot patterns and make decisions. which idea can be inferred from the paragraph above? (a) researchers have used covid - 19 to do more studies using artificial intelligence. (b) covid - 19 is spreading more slowly because of new tools that use artificial intelligence. (c) covid - 19 poses a challenge because people who have it can show no symptoms. (d) more advanced research studies have made it easier for scientists to understand the causes of covid - 19. read the following paragraph from the section listening for coughs. for people with covid - 19, the ai model correctly identified 98.5 percent of people with the disease and correctly ruled out covid - 19 in 94.2 percent of people without the disease. which idea is not supported by the paragraph? (a) researchers need to do more work on the ai model. (b) the ai model makes accurate predictions about who has covid - 19. (c) the ai model has some limitations in its ability to detect covid - 19. (d) the ai model is very effective in detecting covid - 19.

Explanation:

1. Analyze the first - paragraph: It states that people with COVID - 19 who seem healthy can spread the disease, which implies a challenge as symptom - less carriers are hard to detect. Option A is not mentioned as there is no talk of using COVID - 19 for more AI studies. Option B is incorrect as there is no indication that COVID - 19 is spreading more slowly due to AI tools. Option D is not in the passage as there is no mention of advanced research studies helping understand the causes of COVID - 19.
2. For the second - paragraph, it focuses on the accuracy of the AI model in identifying COVID - 19 cases and non - cases. Option A about researchers' future work on the AI model is not supported. Option B about the AI model making accurate predictions about who has COVID - 19 is consistent with the paragraph as it gives the correct identification and ruling out percentages.

Answer:

1. C
2. B
