Please analyze and identify the transition devices used in the following paragraph. Transitions are the glue that holds a paragraph together. These devices lead the reader from sentence to sentence, smoothing over the gaps between by indicating the relationship between the sentences. If this glue is missing, the paragraph will almost inevitably sound choppy or childish, even if every sentence in it responds to a single topic commitment. However, transitions are not substitutes for topic unity: like most glue, they are most effective when joining similar objects, or, in this case, similar ideas. For example, in a paragraph describing a chicken egg, no transition could bridge the gap created by the inclusion of a sentence concerned with naval losses in the Civil War. In other words, transitions can call attention to the topic relationships between sentences, but they cannot create those relationships.
