The first sentence of the correct arrangement must provide information about the subject of the passage. The subject of this passage is 'difficulty in weather forecasting' as indicated by 1.

Out of all the given sentences, the sentence that further talks about the subject is 'Sentence Q'. Therefore, Q forms the first sentence of our correct arrangement.

Keeping 'Sentence Q' in mind we would derive the second sentence of the right arrangement. Q talks about how the ‘different things affect the weather ’, therefore, giving us hint that the following sentence should mention of the variation in the weather. This condition is fulfilled only by 'Sentence P'. Therefore, we may conclude that 'Sentence P' forms the second sentence of our correct arrangement.

If we look at the last sentence of the arrangement i.e. 6, it talks about how someone makes weather forecasts without the help of machines or instruments. The only sentence that introduces the topic of weather forecasting without instruments is 'Sentence S', making it the fourth sentence of the arrangement.

Leaving 'Sentence R' as the third sentence of the arrangement.
