Complete Question Explanation
Concept Reference, Strengthen. The correct answer choice is (B).
Here, we're being asked to strengthen the prediction that Belcher and Hu's research into peptides and semiconductors could eventually lead to a commercial application. That means we are looking for new information in the answer choice that will support the idea that the peptides they are researching could eventually be used to create nanocircuits, as discussed in the first paragraph.
Answer choice (A): Sparking renewed interest in possible DNA applications is not going to help Belcher and Hu's research become commercially applicable. Recall from the 1st paragraph that Belcher and Hu are researching peptides, as opposed to the DNA research that others are doing (lines 18-24). We need to strengthen the commercial applications of peptides, not DNA.
Answer choice (B): This is the correct answer choice. From the passage, we know that Belcher and Hu have already found a few peptides that can bind to the crystals of one of the three widely used semiconductor materials (lines 36-44). They have also expanded their targets to 20 more semiconductor materials (lines 48-55). So if it is true that almost any semiconductor material used in a computer circuit could be replaced with any other semiconductor materials and if Belcher and Hu are able to successfully create nanocircuits using even one of those semiconductor materials, then their nanocircuits will likely be able to be able to be substituted in any computer circuit, thus making their research extremely commercially applicable.
Answer choice (C): The number of peptides required to bind to two different crystals is not discussed as something that is important to a commercial application of peptide nanocircuits.
Answer choice (D): The number of peptides they tested does not strengthen the commercial applicability of their research.
Answer choice (E): The expense of their research preventing other scientists from doing similar research does not strengthen whether or not their research will eventually become commercially applicable.
