Rearrange the given parts P, Q and R to form a meaningful sentence: "Technology for P - tracking droughts has Q - grown in leaps and bounds R - forecasting and".

Introduction / Context:
This question tests your skill in rearranging jumbled parts of a sentence into a meaningful and grammatically correct order. The sentence is about technological progress in forecasting and tracking droughts. Such reordering questions assess understanding of sentence structure, logical flow, and collocation in English.

Given Data / Assumptions:

• Given segments are: P: "tracking droughts has"
• Q: "grown in leaps and bounds"
• R: "forecasting and"
• The fixed beginning is "Technology for".
• We must choose the sequence of P, Q, R that creates a smooth and meaningful statement.

Concept / Approach:
A good English sentence usually follows a logical order: subject phrase, then verb phrase, then modifiers. Here, "Technology for forecasting and tracking droughts" should act as a single subject phrase, followed by the verb phrase "has grown in leaps and bounds". So we must arrange the parts so that "forecasting and tracking droughts" comes immediately after "Technology for", and the verb phrase appears after the subject is complete.

Step-by-Step Solution:
Step 1: Identify that "Technology for" must be followed by a noun or noun phrase indicating what the technology is used for. Step 2: Notice that R begins with "forecasting and", and P continues with "tracking droughts has". Together, R and P can combine to form "forecasting and tracking droughts has". Step 3: Place R immediately after "Technology for": "Technology for forecasting and". This starts to look like a natural phrase. Step 4: Add P after R: "Technology for forecasting and tracking droughts has". Now we have the complete subject phrase plus auxiliary verb "has". Step 5: Finally, place Q: "grown in leaps and bounds" to complete the predicate: "Technology for forecasting and tracking droughts has grown in leaps and bounds." Step 6: This order corresponds to R P Q, which matches option "RPQ". Step 7: Check other combinations like P Q R or Q R P and see that they either break the subject phrase or misplace the verb, leading to ungrammatical or awkward sentences.

Verification / Alternative check:
Read the final sentence aloud: "Technology for forecasting and tracking droughts has grown in leaps and bounds." It is clear, grammatical, and meaningful. Now test a wrong order, for example P Q R: "Technology for tracking droughts has grown in leaps and bounds forecasting and" which is clearly ill formed. This comparison confirms that RPQ is the only correct arrangement.

Why Other Options Are Wrong:

• RQP: Gives "Technology for forecasting and grown in leaps and bounds tracking droughts has", which breaks the verb phrase and misorders words.
• PQR: Begins with "Technology for tracking droughts has grown in leaps and bounds forecasting and", leaving "forecasting and" stranded at the end.
• QRP: Starts with "Technology for grown in leaps and bounds forecasting and...", which is ungrammatical.
• PRQ: Produces "Technology for tracking droughts has forecasting and grown in leaps and bounds", which is also incorrect.

Common Pitfalls:
A frequent error is to focus only on local pairings of words and ignore the overall sentence structure. Another pitfall is to end the sentence with an incomplete phrase like "forecasting and", which clearly cannot stand at the end. To solve such questions efficiently, first identify the main subject and verb, then ensure that any compound phrases, like "forecasting and tracking droughts", remain together in a logical order.

Final Answer:
The correct order of the parts is RPQ, giving the sentence "Technology for forecasting and tracking droughts has grown in leaps and bounds.".
