A dentist is scheduling ten appointments, five on each of two consecutive days. These appointments may be for cleanings, fillings, or root canals, according to the following rules: No more than two root canals can be scheduled on the same day. Root canals must be scheduled before noon. In total, at least three fillings must be scheduled between the two days. All but four of the appointments have been scheduled already, as shown in the table below. Masha, Melissa, Sanjay, and Xavier will take the remaining four time slots, one time slot each. Xavier needs a root canal and Sanjay is not available after 11 a.m. on Day 2. Day 1 Day 2 9:00 am 10:00 am Root Canal Cleaning 11:00 am Root Canal Cleaning Noon Cleaning 1:00 pm Cleaning In the table below, select Must occur for the appointment that is certain to occur as described in The statement, and select Cannot occur for the appointment that is certain not to occur as described in the statement.

Xavier needs a root canal and Sanjay is not available after 11 a.m. on Day 2. Day 1 Day 2 9:00 am 10:00 am Root Canal Cleaning 11:00 am Root Canal Cleaning Noon Cleaning 1:00 pm Cleaning No more than two root canals can be scheduled on the same day Root canals must be scheduled before noon........ 2 root canals done on Day 1, so any root canal will be done on day 2 before noon . Thus Xavier MUST be at 9:00 am on Day 2. In total, at least three fillings must be scheduled between the two days........... . There are no fillings confirmed . So the remaining 4 have to be 3 fillings and 1 root canal of Xavier In the table below, select Must occur for the appointment that is certain to occur as described in The statement, and select Cannot occur for the appointment that is certain not to occur as described in the statement. Make only one selection in each column. Sanjay’s appointment is on Day 1............. YES, Sanjay must be getting his filling done and on day 1. Sanjay’s appointment is at 9 a.m..............Not necessary, as the restriction on time is only on day 2. Masha’s appointment is on Day 1.....There are no restriction as far as Melissa and Masha are concerned Melissa’s appointment is at noon. Melissa’s appointment is on Day 2. The 1 p.m. appointment on Day 1 is for a cleaning......... CANNOT be true, because remaining 3 slots are for filling apart from 1 root canal

Shouldn't the question need to mention that Root Canal, Filling and Cleaning - are 3 different kind of services available at the clinic?
