The $^{1} \mathrm{H}$ NMR spectra of two carboxylic acids with molecular formula $\mathrm{C}_{3} \mathrm{H}_{5} \mathrm{O}_{2} \mathrm{Cl}$ are shown below. Identify the carboxylic acids. (The "offset" notation means that the farthest-left signal has been moved to the right by the indicated amount to fit on the spectrum; thus, the signal at 9.8 ppm offset by 2.4 ppm has an actual chemical shift of $9.8+2.4=12.2 \text { ppm. })$
