Read the given sentence to find out whether there is any

Solution

Part A- The error is in the phrase "the wall's colour". The correct form should be "the colour of the wall". Inanimate objects like 'walls' typically don't use possessive apostrophes, so it's more appropriate to describe the colour as belonging to or being part of the wall without the possessive form. Part E - "Elegant" [adjective] should be replaced with "elegance" [noun]. The possessive determiner "its" needs to be followed by a certain noun. "Elegance" would fit better in describing the simplicity and beauty of the wall. The corrected sentence: The colour of the wall, a soothing shade of sky blue, brightens the room, evoking a sense of tranquillity and serenity in its simple elegance.
