• C. Arts Summary
• D. Second Summary

The number of digits in the main class number corresponds to the summary level. 1 digit (hundreds place) = First Summary. 2 digits (tens place) = Second Summary. 3 digits (ones place) = Third Summary.

Answer 1

The Correct Option is B

Step 1: Understand DDC Summaries. The Dewey Decimal Classification (DDC) system is organized hierarchically. To provide an overview, it uses three levels of summaries. \[\begin{array}{rl} \bullet & \text{First Summary: Lists the 10 main classes (000-900). Example: 600 - Technology.} \\ \bullet & \text{Second Summary: Lists the 100 divisions (the 'tens' place). Example: 610 - Medicine & health.} \\ \bullet & \text{Third Summary: Lists the 1000 sections (the 'ones' place). Example: 611 - Human anatomy.} \\ \end{array}\]

Step 2: Place the number 611 in the hierarchy. The number 611 is a three-digit number representing a specific section within the DDC. \[\begin{array}{rl} \bullet & \text{600 (First Summary)} \\ \bullet & \text{610 (Second Summary)} \\ \bullet & \text{611 (Third Summary)} \\ \end{array}\] Therefore, the class number 611 would be found in the Third Summary.
