Meaning: In this context, 'fight' refers to the ongoing struggle or effort to combat cancer.

Wrong options:

• life: The word 'life' does not convey the action of combating cancer and is too broad in meaning.
• cure: While 'cure' relates to the outcome of treatment, it does not represent the ongoing effort or struggle against cancer.
• journey: The term 'journey' implies a process or experience, which does not specifically denote the active struggle against cancer.

Correct answer: eliminate

Explanation: The verb 'eliminate' is appropriate as it indicates the action of removing or destroying cancer cells, which is the goal of immunotherapy, fitting both grammatically and contextually.

Meaning: 'Eliminate' means to completely remove or get rid of something, in this case, cancer cells.

Wrong options:

• camouflage: 'Camouflage' suggests hiding or concealing, which contradicts the goal of targeting cancer cells for destruction.
• nurture: 'Nurture' implies care and support, which is not relevant to the action of attacking cancer cells.
• synchronize: 'Synchronize' means to occur at the same time, which does not relate to the action of dealing with cancer cells.

Correct answer: where

Explanation: The word 'where' serves as a conjunction that introduces a clause providing additional information about the process of adoptive cell therapy, fitting grammatically and contextually into the sentence.

Meaning: In this context, 'where' indicates the specific situation or condition under which T cells are modified and reintroduced.

Wrong options:

• in that: 'In that' is a phrase that explains a reason but does not fit the context of describing a location or situation.
• while: 'While' suggests a contrast or simultaneous action, which does not accurately describe the process being explained.
• which: 'Which' is a relative pronoun that would require a preceding noun to refer back to, making it less suitable in this context.

Correct answer: broader

Explanation: The adjective 'broader' is suitable as it describes an expanded range of cancers that immunotherapy strategies aim to address, fitting both grammatically and contextually.

Meaning: 'Broader' means wider in scope or extent, indicating that the strategies are being applied to more types of cancers.

Wrong options:

• sharper: 'Sharper' implies a more acute or intense quality, which does not relate to the range of cancers.
• heavier: 'Heavier' suggests weight or burden, which is not relevant to the context of cancer types.
• deeper: 'Deeper' implies more profound or intense, which does not accurately describe the range of cancers being targeted.
