a level spectroscopy help

Hello I keep getting the M/Z value wrong for mass spectroscopy and I also sometimes find it hard to know if I should include a wavelength value in infrared spectroscopy.
For example for Mass spectroscopy in this example: https://ibb.co/x6dYMWN
Allery says it's 58 M/Z and hence 58 Mr but isn't 60 M/Z the last peak shown in this graph?
For infrared spectroscopy:

Do we include that little peak right after 1500? Are the two peaks around 3000 counted as separate peaks or is it considered a broad peak?
This whole topic feels like doing those google captchas where you think to yourself "should I include this" when the thing they are asking for has one pixel on the photo lol.
What should I do for these spectras?

You pay attention to the peaks with the strongest intensity in MS. As the IR spectrum shows that it is an alcohol (broad peak at around 3300cm-1) and only saturated C-H stretching (2 separate absorption peaks below 3000 cm-1), the relative molecular mass of 58 fits a saturated 4-carbon alcohol. The peak above 1500cm-1 is not a carbonyl absorption peak which must be the strongest peak in the IR spectrum. I always advise my students, practice makes perfect. Work on as many problems as possible. There is no easier way to learn organic chemistry.
