Meaning: 'Generate' means to produce or create something, particularly in a systematic way.

Wrong options:

• create: 'Create' is a synonym of 'generate' but is less commonly used in scientific contexts for producing data or tags.
• get: 'Get' implies obtaining something rather than producing it, which does not fit the context of making a unique identification tag.
• make: 'Make' is too informal for this context and does not convey the systematic process implied by 'generate.'

Correct answer: stretch

Explanation: The word 'stretch' is appropriate as it refers to a segment or portion of DNA, fitting grammatically and contextually with the description of a unique identification tag.

Meaning: 'Stretch' in this context refers to a specific segment or length of DNA that is being analyzed.

Wrong options:

• line: 'Line' is too vague and does not specifically refer to a segment of DNA, making it less precise than 'stretch.'
• period: 'Period' does not relate to DNA and suggests a time frame rather than a segment, making it contextually irrelevant.
• cut: 'Cut' implies a physical action rather than a segment of DNA, which does not fit the intended meaning.

Correct answer: extracted

Explanation: The verb 'extracted' is the correct choice as it indicates the process of obtaining DNA from a source, fitting grammatically and contextually with the sentence's focus on obtaining genetic material.

Meaning: 'Extracted' means to remove or obtain something from a larger whole, in this case, DNA from cells.

Wrong options:

• bought: 'Bought' implies a purchase, which is not relevant to the context of obtaining DNA.
• made: 'Made' suggests creation rather than obtaining, which does not fit the context of DNA extraction.
• get: 'Get' is too informal and does not convey the specific scientific process of obtaining DNA.

Correct answer: boon

Explanation: The word 'boon' fits well as it conveys a positive benefit or advantage, aligning with the context of aiding taxonomists. It is grammatically correct and contextually appropriate.

Meaning: 'Boon' refers to something that is beneficial or helpful, particularly in a significant way.

Wrong options:

• gift: 'Gift' implies a present rather than a beneficial tool, making it less suitable in this context.
• present: 'Present' also suggests a gift rather than a beneficial tool, which does not fit the intended meaning.
• curse: 'Curse' has a negative connotation and contradicts the positive context of aiding taxonomists.

Correct answer: realm

Explanation: The word 'realm' is appropriate as it refers to a field or area of activity, fitting grammatically and contextually with the discussion of public health.

Meaning: 'Realm' means a domain or area of interest, particularly in a specific field like public health.

Wrong options:

• period: 'Period' refers to a duration of time and does not relate to a field of activity.
• world: 'World' is too broad and does not specifically indicate a field or area of focus.
• range: 'Range' implies variety but does not convey the specific area of public health as effectively as 'realm.'

Correct answer: transmit

Explanation: The verb 'transmit' is the correct choice as it indicates the action of spreading diseases, fitting grammatically and contextually with the sentence's focus on mosquito-borne diseases.

Meaning: 'Transmit' means to pass on or spread something, particularly in the context of diseases.

Wrong options:

• cure: 'Cure' implies healing rather than spreading, which contradicts the context of disease transmission.
• have: 'Have' is too vague and does not convey the action of spreading diseases.
• visualize: 'Visualize' refers to seeing or imagining something, which is irrelevant in the context of disease transmission.
