Answer to Question 1

ANS: C
In ILDs, the FEV1/FVC ratio is preserved or even supranormal.

Answer to Question 2

ANS: C
The plain chest radiographic and HRCT features of IPF often are considered the classic ILD pattern, primarily because, next to sarcoidosis, IPF is the most common ILD and because several other ILDs have a similar appearance.
