Practice Listening: Multiple Choice, Single Answer ID: #33877 Short Paramount problem
Instructions ›
Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

Currently, the paramount problem in the field of biomaterials, the science of replacing diseased tissue with human-made implants, is control over the interface, or surface, between implanted biomaterials and living tissues. The physical properties of most tissues can be matched by careful selection of raw materials: metals, ceramics, or several varieties of polymer materials. Even the requirement that biomaterials processed from these materials be nontoxic to host tissue can be met by techniques derived from studying the reactions of tissue cultures to biomaterials or from short-term implants. But achieving necessary matches in physical properties across interfaces between living and non-living matter requires knowledge of which molecules control the bonding of cells to each other—an area that we have not yet explored thoroughly.

Option 2: "discuss the current state of technology in the field of biomaterials"

Explanation: The text outlines the current challenges in biomaterials, particularly regarding the interface between implants and living tissues. This aligns with discussing the current state of technology, as it highlights existing methods and the need for further exploration in the field.

Option 1: "answer a theoretical question in the field of biomaterials"

Explanation: The text does not focus on answering a theoretical question; instead, it discusses practical challenges in biomaterials. The author's emphasis is on the current problems and knowledge gaps rather than theoretical inquiries.

Option 3: "predict an ethical crisis for"

Explanation: The text does not mention any ethical concerns or crises. It focuses solely on the technical aspects and challenges of biomaterials, making this option irrelevant.

Option 4: "resolve a research dispute in the field of biomaterials"

Explanation: The text does not address any disputes or conflicts in research. Instead, it presents a unified view of the challenges faced in biomaterials, indicating a lack of resolution rather than a focus on resolving disputes.
