a lovely yellow rose was the resting place for the butterfly.

Answer 1

Under line
yellow rose was the resting place

Hope I helped

Answer 2

underline lovely yellow rose and circle rose, because it's talking about a rose and what its doing (being a resting place for the butterfly) so it's the subject but the complete subject is the subject and the describing words lovely and yellow describe the rose
