I agree.

To determine the correct order of the Library of Congress call numbers, we need to understand how Library of Congress call numbers are structured. Library of Congress call numbers are alphanumeric codes that are used to classify and organize books and other materials in the Library of Congress.

Each call number consists of a combination of letters and numbers. The letters at the beginning of the call number are usually indicative of the subject or topic of the book, while the numbers following the letters represent additional information such as the author, title, edition, and publication year.

To determine the correct order of the call numbers in the given sets, we need to compare the letters and numbers in each call number. In this case, let's analyze the sets one by one:

A. E88 G2512 S57 1998, E88 G62 D225, E88 G62 L166 1995, E88 G62 L45
B. E88 G62 L166 1995, E88 G62 L45, E88 G62 D225, E88 G2512 S57 1998
C. E88 G2512 S57 1998, E88 G62 D225, E88 G62 L45, E88 G62 L166 1995
D. E88 G62 D225, E88 G62 L166 1995, E88 G62 L45, E88 G2512 S57 1998

By comparing the letters and numbers in each set, we can see that Set B (E88 G62 L166 1995, E88 G62 L45, E88 G62 D225, E88 G2512 S57 1998) is in the correct order. Therefore, the correct answer for question #20 is B.

Please note that this is just one method of determining the correct order of the call numbers. In a real library setting, there may be additional rules or considerations that need to be taken into account.
