Rearrange the parts of the sentence on threats to nation building in the correct order to form a coherent paragraph.

Introduction / Context:
This jumbled paragraph describes the threats to nation building and suggests solutions. The sentences are labelled P, Q, R, and S. The goal is to place them in a sequence that moves logically from problem statement to explanation and then to suggested actions and conclusions.

Given Data / Assumptions:

Q: Threats to our nation building processes are increasing day by day.
P: When one gets solved or nears the solution, other starts raising its ugly head.
S: The need of the day is to go for integrated approach with taking steps to solve the poverty, illiteracy and population problems along with tough steps and stern action against the terrorists.
R: Tougher punishments should be provided for them in order to weed them out completely.
We must create a coherent mini paragraph.

Concept / Approach:
A well formed paragraph begins with the main idea or problem, then elaborates on it, and finally suggests remedies. Q clearly states the main problem: threats to nation building processes are increasing. P then describes how when one problem is solved, others arise, which elaborates on Q. S logically follows by stating what is needed: an integrated approach that deals with poverty, illiteracy, population, and terrorism. R finally specifies one strong measure against terrorists: tougher punishments. This gives the order Q P S R, which matches option QPSR.

Step-by-Step Solution:
Step 1: Identify the sentence that introduces the topic. Q mentions "Threats to our nation building processes" and clearly sets up the issue, so it must come first. Step 2: Add a sentence that naturally follows the idea of increasing threats. P explains that when one threat is solved, another arises, illustrating the problem described in Q. Step 3: Once the problem is clear, the paragraph should move towards solutions. S states "The need of the day is to go for integrated approach", which fits well after understanding the nature of the threats. Step 4: Finally, R gives a specific solution related to the terrorists mentioned in S: providing tougher punishments to eliminate them. Step 5: Thus, the correct order is Q P S R, corresponding to option QPSR.

Verification / Alternative check:
Reading the paragraph in the order QPSR gives a smooth structure: the first sentence identifies growing threats; the second illustrates their continuing nature; the third recommends an integrated approach to solve root problems and terrorism; the fourth focuses on one strong measure against terrorists. Any other order either presents specific remedies before stating the main need or introduces the need before fully describing the problem. QPSR is the only option that goes from general problem to specific remedy in a clear and organized way.

Why Other Options Are Wrong:

SRQP: Starting with S discusses "The need of the day" without first explaining what the problem is. It feels abrupt and incomplete.
RSQP: Beginning with R talks about tougher punishments without establishing who is being punished or why. The context comes later, so this order is confusing.
QRSP: Q followed by R jumps from a general problem to a specific solution for terrorists without the explanatory link in P or the integrated plan in S.
PQRS: P cannot open the paragraph because it speaks of "one" problem already being solved without saying what that problem is or introducing threats in general.

Common Pitfalls:
Students may be misled by sentences that look dramatic or strongly worded and place them at the beginning. However, good paragraphs usually begin with a balanced general statement that defines the topic. Always identify which sentence introduces the main subject and which ones give examples, explanations, and final recommendations.

Final Answer:
The correct arrangement of the parts is QPSR.
