Five sentences related to a topic are given below. Four of them can be put together to form a meaningful and coherent short paragraph. Identify the odd one out.

1. Much has been recently discovered about the development of songs in birds.

2. Some species are restricted to a single song learned by all individuals, others have a range of songs.

3. The most important auditory stimuli for the birds are the sounds of other birds.

4. For all bird species there is a prescribed path to development of the final song,

5. A bird begins with the subsong, passes through plastic song, until it achieves the species song.

On reading the sentences, we can infer that the paragraph talks about the development of songs in birds. 

1 should be the opening sentence since it introduces the topic of discussion, the development of songs in birds. 1 provides a proper introduction to the paragraph by stating that much has been discovered about the development of songs in birds. 

4 should be the sentence that follows 1 since it states that the development of songs in birds follow a template process. 
5 explains the mechanism in which the song is developed. Therefore, sentence 5 should follow sentence 4. 
2 should be the last sentence since it states that some species restrict themselves to one song while other species have more than one song. 

Sentences 1452 form a coherent paragraph. Sentence 3 talks about the sounds of birds while the other sentences are about how a species develops a song. Therefore, sentence 3 is the one out of context and hence, 3 is the right answer.
