Question

The following text is from a fictitious personal blog.

[1] In recent years, many people have turned from dairy milk to plant-based milks, such as soy or almond milk, with the hope that they will be drinking a more nutrisious product. [2] The use of plant-based milks is widespread enough that there is substantial value to questioning this assumption: Is the use of such products truly healther? [3] Aparently so. [4] I have seen data on U.S. News and World Report that fortified soy milk contains as much protein and calcium as cow’s milk, and less sugar. [5] Speaking only for myself, this comes as a substantial frustration: I strongly prefer the smooth and familiar taste of dairy to its pungent and sometimes oddly textured plant-based counterparts. [6] Frankly, I highly doubt that these data are true.

Which element most signals bias in this source?

the use of evidence from a one-sided source
the inclusion of excessive emotional appeals
the use of diction that does not create an objective tone
the inclusion of bold generalizations about people who prefer plant-based milk

Answer 1

the use of diction that does not create an objective tone

The writer uses subjective, negative language ("pungent," "oddly textured," "I strongly prefer," "I highly doubt") and first‑person remarks, which signal personal bias rather than an objective presentation of the issue.
