1. (b) suggest more careful evaluation of a type of business investment (Because investment in service might not lead to any advanage as suggested by the example of the bank)
2. (c) basis on which they need to be weighed (Because "Investments in service, like those in production and distribution, must be balanced against other types of investments")
3. (a) It enabled the bank to retain customers at an acceptable rate (Because the regional bank invested " in reducing the time a customer had to wait for a teller" and as such the bank was providing service reasonably which was acceptable to the customers)
4. (d) was an innovation that competing banks could have imitated (Because the last para tells that the bank did not analyze "their service improvement to determine whether it would attract new customers by producing a new standard of service that would excite customers or by proving difficult for competitors to copy")
5. (d) It provides an example of the point about investment in service made in the first paragraph (Because the first para tells that the investment in service might not be advantageous and in the second para he gives the example of one regional bank)
6. (b) emphasize the relatively low value of the investment in service improvement (Because the investment in service improvement did not prove to be advantageous to banks by way of acquiring new customers so the only advantage is that they can explain their service improvement to their existing customers)
7. (b) explaining two different kinds of immunological reactions (Because the first reaction is the typical "antigen-antibody immunological reaction") and the second reaction as suggested by para 2 is "cell-mediated immunity")
8. (d) antigens have no apparent mechanism to direct the formation of an antibody (Because "When molecular biologists discovered, moreover, that such information cannot flow from protein to protein, but only from nucleic acid to protein, the theory that an antigen itself provided the mold that directed the synthesis of an antibody had to be seriously qualified")
9. (d) is a partial explanation (Because the author does not discard this theory but goes on to discuss the second king of immunological reaction i.e., cell mediated immunity)
10. (c) destruction of antibodies (Because the second para tells that "the primary difficulty with the antigen-antibody explanation is the informational problem of how an antigen is recognized and how a structure exactly complementary to it is then synthesized" and the third para suggests that "Such lymphocytes do not give rise to antibody-producing plasma cells but themselves bring about the death of the foreign-tissue cells")
11. (a) I only (Because the third para tells that "Such lymphocytes do not give rise to antibody-producing plasma cells")
12. (b) proteins could have been shown to direct the synthesis of other proteins (Because "When molecular biologists discovered, moreover, that such information cannot flow from protein to protein, but only from nucleic acid to protein, the theory that an antigen itself provided the mold that directed the synthesis of an antibody had to be seriously qualified.")
13. (a) I only (Because the first para tells that "antigenic particles are engulfed by and very often digested by macrophages and polymorphs." and the third para tells that "Such lymphocytes do not give rise to antibody-producing plasma cells but themselves bring about the death of the foreign-tissue cells")
14. (b) explaining how cell mediation accounts for phenomena that the antigenantibody theory cannot account for (Because the second para tells that "the theory that an antigen itself provided the mold that directed the synthesis of an antibody had to be seriously qualified" and then "realize that a second immunological reaction is mediated through the lymphocytes that are hostile to and bring about the destruction of the antigen")
