We can call this passage a Bridge Theme. It continues the mood of the first theme, since it is based on the same C major triad. This time, it is announced by the horns, clarinets, oboes and flutes, and continued by the violins.
Although the first phrase began with the C major triad, it ends on the dominant. This is further reinforced by the low strings and double bassoons, which play an ascending arpeggio and then a descending chord.
The second phrase brings us back to the tonic with the arpeggio, which is based again on the C major chord. It seems as if a question and its answer have just been introduced.
If you carefully listen once more to these phrases, you will be able to recognize the Fate Motive in the arpeggio passages.
