Ten Logical reasoning · Decisions questions with answers
Try each one, then open the answer. These ten stay the same; the test draws new ones every time.
1. Statement I: The college library now stays open until 10 pm. Statement II: More students now use the library in the evenings. Statement III: Before the exams, students asked for longer library hours. Which order shows cause leading to effect?
A
III → I → II
B
II → I → III
C
I → III → II
D
II → III → I
Show answer
Answer: A. The students' request (III) led to the longer hours (I), which allowed more evening use (II). Putting II first reverses the chain, since evening use followed the new hours.
2. Infection rates are rising in a hospital's wards, and an audit shows that staff wash their hands much less often than they should. Which course of action logically follows?
A
Put hand-rub dispensers at every bedside and check hand hygiene regularly
B
Give every patient antibiotics on admission
C
Stop admitting new patients
D
Dismiss all ward nurses
Show answer
Answer: A. Poor hand hygiene is the identified cause, so making hand-rub easy to reach and auditing it acts directly. Routine antibiotics increase resistance, and the other options are extreme.
3. Statement I: Fewer patients came to the hospital outpatient department on Eid day. Statement II: Most shops in the city were closed on Eid day. Which is correct?
A
Statement I is the cause and Statement II is its effect
B
Statement II is the cause and Statement I is its effect
C
Both statements are effects of a common cause
D
The statements are independent of each other
Show answer
Answer: C. Closed shops do not keep patients away from hospital, nor the other way round. Both result from the Eid holiday, a common cause.
4. A hospital's only lift has been out of order for two weeks, and patients who cannot walk are being carried up the stairs. Which course of action logically follows?
A
Ban visitors from the upper floors
B
Repair the lift urgently and treat patients who cannot climb on the ground floor until then
C
Move the whole hospital to a new building
D
Stop admitting patients who cannot walk
Show answer
Answer: B. Repairing the lift fixes the cause, and ground-floor care protects patients meanwhile. Turning patients away or moving the hospital is unreasonable.
5. A school's mathematics pass rate dropped sharply in the first year of a new board syllabus. Which course of action logically follows for the school?
A
Remove mathematics from the timetable
B
Expel the students who failed
C
Stop entering students for the board examination
D
Train its teachers in the new syllabus and review their lesson plans
Show answer
Answer: D. The fall came with the new syllabus, so the school should prepare its teachers for it. The other options punish students or abandon the subject instead of fixing the cause.
6. A medical college finds that many first-year students fail anatomy because they struggle with lectures and books in English. Which course of action logically follows?
A
Refuse admission to students from Urdu-medium schools
B
Cancel the anatomy examination
C
Arrange extra English support classes for first-year students
D
Halve the anatomy syllabus for weaker students
Show answer
Answer: C. The cause is weak English, so English support helps students follow anatomy. Refusing admission is unfair, and cancelling or cutting the course lowers the standard of medical training.
7. Statement I: Several patients at a clinic developed stomach infections last month. Statement II: Water from the clinic's drinking water cooler was found to contain harmful bacteria. Which is correct?
A
Statement I is the cause and Statement II is its effect
B
Statement II is the cause and Statement I is its effect
C
Both statements are effects of a common cause
D
The statements are independent of each other
Show answer
Answer: B. Contaminated drinking water causes stomach infections, so II is the cause and I the effect. Reading the order of the statements as the order of cause and effect leads to the first option.
8. A college library finds that many borrowed books are returned torn or damaged. Which course of action logically follows?
A
Stop lending books altogether
B
Close the library
C
Check books on return and charge a fine for damage
D
Stop buying new books
Show answer
Answer: C. Checking returned books and fining damage discourages careless use while keeping the service. Stopping lending or closing the library harms every reader.
9. A city has introduced a heavy fine for using a mobile phone while driving. Which of the following is the most likely effect?
A
More people buy mobile phones
B
Petrol prices rise in the city
C
Fewer drivers use mobile phones while driving
D
More cars come onto the city's roads
Show answer
Answer: C. A heavy fine discourages the behaviour it targets, so fewer drivers use phones at the wheel. The other options have no link to the fine.
10. An examination board learns that its chemistry paper was leaked a few hours before the exam. Which course of action logically follows?
A
Postpone the chemistry paper, set a new one and find the source of the leak
B
Cancel all examinations for the year
C
Hold the exam as planned
D
Give every candidate full marks in chemistry
Show answer
Answer: A. Only one paper is affected, so a new paper and an inquiry keep the exam fair. Holding the leaked paper is unfair, and cancelling everything is out of proportion.
