Answer to Question 1

C

Answer to Question 2

Data elements included in data flows also appear in the data model, and vice versa. You must include in the data model any raw data captured and retained in a data store, and a data model can include only data that have been captured or that have been computed from captured data. Because a data model is a general business picture of data, both manual and automated data stores will be included. Each data store in a process model must relate to business objects represented in the data model. You can use an automated repository to verify these linkages.

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
