The answer is likely to depend on your jurisdiction. (I am not a lawyer, this is not legal advice)
In general, facts are not subject to copyright. However, the text might be. If it is possible to rephrase the text without changing the meaning, that tends to be an indication of copyright. Depending on the jurisdiction there might be exemptions which allow you to use it despite the copyright. In US law this is called 'fair use', and some other jurisdictions call it 'fair dealings'. Scientific non-profit work like a thesis tends to fall under such a provision.
You should contact support and mention more details about your proposed usage (and mention your jurisdiction). Alternatively, you could contact a lawyer. You may also ask your supervisor, who might be able to point you to the legal aid services of your school/university or country.
