Look at each of the statements and the given information in the paragraphs to determine whether they are justified or not.

I. An individual who is experienced in fitness and has taken 3 group classes can choose to pay for the individual direction membership.

Look at the bolded sentence in the techniques paragraph,

At a gym there are three different paths an individual can take to obtaining membership. The first option is personal training. The second option is group fitness classes and the last option is individual direction. Members are only allowed to partake in individual direct after 5 personal training sessions and 10 group fitness classes.

Therefore, statement I. is not justified.

II. An individual who has a budget of $160 a month to spend on fitness after going through the personal training and group sessions can attend 8 classes per month.

Look at the bolded sentence in the price paragraph,

The price of membership depends on the technique the individual chooses. Personal training costs any where between $40 and $75 per session depending on the trainer. Group fitness classes cost $20 per session and individual direction costs $15 per visit.

Therefore, statement II. is justified.

III. Tina has completed all the necessary requirements to have an individual direction membership; Tina would make the 26th member of this type.

Look at the bolded sentence is the personnel,

For personal training, there must be one trainer per individual. For group fitness classes there must be one trainer per eight individuals. For individual direction, no trainer is required however, only 25 members can part take in individual direction at a time. At this particular gym there are 12 trainers. 

Therefore, statement III. is not justified.

I. There are 20 watercolor paintings, 12 pottery pieces, and 28 pointillism pieces in the art exposition.

Looking at the bolded sentence from the third paragraph,

A art school is holding an exposition to highlight their student talent. The exposition requires a third of the art work to be watercolor paintings and a fifth to be pottery pieces. 

Therefore statement I. is justified.

II. Students that will be featured in the school's exposition require a least a days notice.

Looking at the bolded sentence from the second paragraph,

A pointillism piece that has dimensions of 12x18 takes on average 15 hours to create. A watercolor painting that is 17x23 takes on average 20 hours to create. A piece of pottery that has dimensions 6x2x4 takes 12 hours to create.

Since the longest an art piece takes to create is 20 hours, one days notice, although not desired, is acceptable. Therefore, statement II. is justified.

II. Timothy is known for his watercolor pieces and is expected to paint 4 for the school's exposition. Timothy can create all the pieces over the weekend (Saturday and Sunday).

Since a watercolor painting takes 20 hours and Timothy needs to create 4, that means it will take him 80 hours to complete them. Since there are only 24 hours in a day, Saturday and Sunday only gives 48 hours therefore, statement III. is not justified.
