CrPC vs. BNNS: Where's My Bailment?!

Yaar, I'm freaking out, scored 42/100 on CrPC & BNNS in last week's CUET PG Law mock test. My brain's fried after 3 hours of non-stop studying, but let's get down to business. Question 12 was a stunner: "What's the difference between 'bailment' and 'pledge'?" - duh, 2 hours wasted on this question alone. Turns out, bailment (sec. 148 CrPC) is like lending someone something - they have possession but not title, whereas pledge (sec. 172 BNNS) is when you lend something with the intent of getting it back, but it's still with the borrower. I answered pledge for bailment, yaar, that's a -8 for me. I scored badly on sections 174 (Police inquests) and 190 (Public nuisances).
