Answer 2

Trembling oars:

“Trembling oars” comes under the personification figure of speech. Trembling is the describing word used for living beings or humans. But here, it is used with the non-living object. So, the trembling is specifically giving personification of the object.

Personification creates here the description of ores that are non- living but trembling is the word which specifies the qualities of humans. In such cases, personification is the best figure of speech. For example, Time and tide wait for none. Here, also the non-living things are explained using the words that describe about living things.
