TACHS: Details in a notice: match the rule to the exact question

Learn to find one specific rule in a notice full of times, places and requirements, and to read the small words like must, may, only and but that decide who a rule covers and what it allows.

Updated October 3, 2026

A notice lists many places, times and rules. How do you find the one that answers the question?

Short answer

Pick out the action and the person in the question, find the sentence about that exact action, and read the sentence after it. Watch must, may, only and but, because a permission and a requirement often sit side by side.

Know first: Scanning a passage for key words, The difference between may and must

Step 1 of 5

A notice is full of real details attached to the wrong question

Some TACHS Reading passages are practical: a notice, a set of rules, a schedule. Detail questions ask what the text says about one specific thing. The answer is usually in a single sentence.

The trouble is that a notice holds many places and times. Wrong answers are often real details from the same notice, attached to the wrong rule. You need the sentence about exactly what was asked.

Small words that change a rule
WordWhat it signalsExample
mayPermission: you are allowedYou may bring a snack.
mustRequirement: you have toSnacks must stay in your bag.
onlyThe rule covers one group or caseonly students on the list
butThe real rule often comes right aftermay browse, but must pay at the desk
will not changeSomething stays as it wasThe start time will not change.

When may and must appear together, read both parts and check which one the question asks about.

Step 2 of 5

Separate the permission from the requirement

Book fair notice

The spring book fair runs Monday through Thursday in the gym1. Students may browse during lunch2, but all purchases must be made at the library desk3. Bring cash or a check; the fair cannot accept cards. Classes will visit together with their teachers on Tuesday afternoon4.

  1. Where the fair is held. A tempting wrong place.
  2. Permission, and a time, not a place.
  3. The requirement about paying.
  4. A separate detail about class visits.

Worked example: Where to pay

According to the book fair notice, where must students pay for books?

  1. AIn the gym
  2. BAt the library desk
  3. CIn the lunchroom
  4. DIn their classrooms on Tuesday
  1. 1

    Key words

    Where and pay.

  2. 2

    Find the sentence

    All purchases must be made at the library desk.

  3. 3

    Notice the but

    Browsing is allowed in one place. Paying happens in another.

  4. 4

    See why the other choices are there

    A is where the fair is held, so it's the most tempting. C comes from during lunch, which is a time. D mixes in the class visit, a separate detail.

Answer

At the library desk.

Wrong: Students may browse during lunch, so they pay in the gym at lunch.

Right: Students may browse during lunch, but they must pay at the library desk.

The permission and the requirement are joined by but. The question about paying is answered by the part after it.

Step 3 of 5

Find the rule for the person in the question

Read this notice

The science fair will be held in the gym on Thursday, March 12. Students may set up their boards from 7:30 to 8:15 that morning, but all electrical projects must be checked in Room 104 before setup. Judges will visit tables from 9:00 to 11:00. Only students in grades 7 and 8 will be judged; younger students may display projects without judging. If the gym floor is being repaired, the fair will move to the library, and the times will not change.

Check yourself · Question 1

Where must students take electrical projects before setting them up?

ATo the gym
BTo the library
CTo the judges' tables
DTo Room 104

Answer: D

The sentence with must says electrical projects must be checked in Room 104 before setup.

Trap answer: To the gym

Right notice, wrong rule

Why it looks right
The gym is the main place in the notice, and setup happens there.
Why it's wrong
The question asks where projects go before setup. The but in the second sentence sends electrical projects somewhere else first.
The right answer
To Room 104.

Check yourself · Question 2

Jada is in sixth grade and has finished a project. According to the notice, what can she do?

ADisplay her project, but it will not be judged.
BHave her project judged between 9:00 and 11:00.
CNothing, because the fair is only for grades 7 and 8.
DSet up her project in the library instead of the gym.

Answer: A

Only limits judging to grades 7 and 8. The same sentence then says younger students may display projects without judging.

Common mistake

I chose the first place the notice mentioned.

Why it's tempting
The main location is in the first sentence, so it feels like the answer to any where question.
Do this instead
Match the place to the action in the question. Find the sentence about that action, and read past any but.

Step 4 of 5

What to remember

Remember

  1. Find the sentence about the exact action in the question, then read the next sentence too.
  2. May gives permission and must sets a requirement; the rule after but is often the answer.
  3. Check who a rule covers: only limits it to one group, and everyone else follows the regular rule.

Step 5 of 5

Practice on a real question
