Look at the following paragraph from page 6 of our primary source:

In 2022, Hillman undertook follow-up research to ascertain if/how student attitudes to censorship had changed since his 2016 study. The results showed significantly increased support for censorship as follows:

• 79% of students believe ‘Students that feel threatened should always have their demands forsafety respected’ (up from 68% in 2016), while 4% disagree (down from 10% in 2016).
• 61% of students say ‘when in doubt’ their own university ‘should ensure all students areprotected from discrimination rather than allow unlimited free speech’ (up from 37% in 2016).
• The proportion of students who believe ‘universities are becoming less tolerant of a wide range of viewpoints’ has risen to 38% (up from 24% in 2016), and this view is considerably more common among male students (51%) than female students (28%).
• The proportion of students who agree that ‘if you debate an issue like sexism or racism, you make it acceptable’ has doubled from the 2016 result to 35% (Hillman, 2022).

Twenge (2017) noted that iGeneration (iGen) (those born from 1995 onwards) differ from previous generations in several significant ways, one being that they tend to grow up more slowly, reaching adult milestones later (e.g. leaving home, dating, having sex, getting a job) and have spent less time unsupervised by adults. Another difference is that iGen exhibits far higher rates of anxiety and depression than previous generations. Twenge’s investigation was in the USA, but trends in the UK indicate that five times the number of first-year undergraduate students declared a mental health problem in 2015/16 compared to 2007/8 (Institute for Public Policy research 2017). iGen probably began arriving on university campuses in 2013, so this stark finding may echo Twenge’s findings. Whilst in 2009/10 male and female students were equally likely to report mental health problems, by 2015/16 female students were more likely to disclose (1.4% male, 2.5% female). Whilst it might be tempting to think that we are only witnessing a broadening of criteria in terms of identification and diagnosis, this theory is belied by the fact that student suicide increased by 79% between 2007 and 2015/16. Student dropout rates increased 210% between 2009/10 and 2014/15 (Institute for Public Policy Research 2017).

This paragraph shows an upward trend in increased anxiety and depression, but which sentence shows that it might NOT ONLY be an issue of diagnosing something that was not diagnosed before?
