Practice Listening: Multiple Choice, Single Answer ID: #38470 Short Organism
Instructions ›
Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

First, children should be vaccinated to protect them from acquiring diseases which may prove to be fatal or cause an incurable disability. There are three types of vaccines. The first is known as a killed vaccine as it is compromised of microorganisms which are killed through various processes. The vaccine for polio is an example of a killed vaccine. The second type of vaccine is known as life attenuated vaccine. This is comprised of living organisms which multiply to a certain extent in the body but do not produce any infection. And finally we have toxoids. Toxoids are bacteria that are made inactive but have the capacity to produce an immune response. Tittanus is an example of such a vaccine.

What differentiates the three types of vaccines?

Option 3: "Whether the organism is live, dead or just inactive"

Explanation: This option correctly identifies the key differentiators of the three types of vaccines as outlined in the text. The text describes killed vaccines (dead organisms), live attenuated vaccines (live organisms), and toxoids (inactive organisms). This aligns perfectly with the main idea of the text, making it the correct answer.

Option 1: "Whether the organism attenuates or kills immunity"

Explanation: This option incorrectly suggests that the differentiation is based on how the organism affects immunity. The text does not mention 'killing immunity' as a factor. Instead, it focuses on the state of the organisms in the vaccines (live, dead, inactive). Therefore, this option does not align with the main idea presented in the text.

Option 2: "Whether the organism is processed, immune or multiplied"

Explanation: This option introduces terms like 'immune' which are not relevant to the differentiation of vaccine types as described in the text. The text specifically categorizes vaccines based on the state of the organisms (live, dead, inactive), not on whether they are processed or immune. Thus, this option fails to accurately reflect the content.

Option 4: "Whether the organism is live, infective or toxic"

Explanation: This option incorrectly uses the term 'infective,' which is not mentioned in the text. The text differentiates vaccines based on whether the organisms are live, dead, or inactive, not based on their infectivity or toxicity. Therefore, this option does not accurately represent the information provided.
