Question

which statement primarily appeals to ethos to support the position that doctored photos of celebrities promote unrealistic beauty standards?
jo swinson, a former member of the british parliament, has shown how important this issue is by campaigning against the unrealistic depiction of women in advertisements.
retouched photographs of celebrities—especially those of women—pose a dangerous problem for children and young adults, who look at the photographs and aspire to impossibly stick - thin legs and eighteen - inch waists.
most celebrities are already uncommonly good - looking, so editing their photographs to hide any perceived imperfections serves to promote an even more unrealistic standard of beauty.

Explanation:

Ethos appeals to credibility or authority to support an argument. The first statement cites Jo Swinson, a former British parliament member, a figure with public credibility, to back the position about doctored celebrity photos and unrealistic beauty standards. The other statements use logical reasoning (logos) about harms to young people and the gap between real and edited celebrity appearances, not authority/credibility.
