Select the sentence that exhibits biased language. A. If an immigrant marries a U. S. citizen, the spouse of the U. S. citizen is deemed an immediate relative. B. A careful scientist should always test his results. C. Over half of the engineering students in the entering class are non-native speakers of English. D. Many restaurant servers state their names to customers.

B. A careful scientist should always test his results.

Explanation:

Biased language is use of words (usually pronouns) and phrases which reflect some kind of stereotype (related to gender, age, sexual orientation, nationality, ethnicity etc.)

Options A, C and D all use neutral terms and phrases (spouse, non-native English speakers, servers state their names) to avoid biased language.

However, option B usis the pronoun "his" to its antecedent "scientist". This suggests that all scientists (or at least all careful scientists) are men, which is of course wrong. This can be avoided by using "their" instead of "his" or "her" or by rewriting the sentence to exclude biased language.

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
