for both problems, true or false?

A substrate containing both an alkene and an aldehyde group, when treated with excess (a lot of) H2 in the presence of Pt,Pd, or Ni, results in a major substrate product containing a primary alcohol group, but no alkene group. The compound known as PCC (pyridinium chlorochromate) will cause a primary alcohol to undergo an oxidation reaction, producing an aldehyde as the final major substrate product
