Final answer:
Based on option 'c', one would predict that the two proteins are structurally similar, given that the context likely involves a comparison of amino acid sequences or structural features, which implies a significant finding regarding their similarity.
Step-by-step explanation:
The structural similarity between two proteins can be predicted by analyzing key features such as their amino acid sequences, three-dimensional shapes, and the functions they perform in the body. If option 'c' refers to a passage that highlights a particular man who discovered the similarity between two proteins, for example, through comparing their amino acid sequences or structural features, one might predict that the proteins are indeed similar. This conclusion would be based on the implication that the passage describes a significant finding in the field of protein structure.
Moreover, if the context in 'c' implies a detailed comparison or alignment of protein structures that was undertaken by the mentioned individual, the prediction for structural similarity would be stronger. Proteins with similar sequences and structural motifs often share functional similarities and could be evolutionarily related, which supports the prediction of structural similarity.
