Which statement is true about words in lowercase compared to uppercase letters?

The assertion that words in lowercase are easier to read is supported by research in typography and cognitive science. Lowercase letters tend to have a more distinct shape compared to uppercase letters, which helps with word recognition. The varied heights of lowercase letters create a more familiar and recognizable word shape, aiding in the reading process. Studies indicate that readers often find lowercase text more comfortable and quicker to process since the brain can recognize words as whole units rather than having to decipher each individual letter.

In contrast, uppercase letters are uniform in height and can lead to a more monotonous appearance, making words harder to distinguish as units. Consequently, using lowercase letters in most text facilitates fluency in reading and enhances comprehension, demonstrating why the choice indicating that lowercase letters are easier to read is accurate.
