You will be provided with a reference and some statements. Please determine whether each statement is 'supported', 'unsupported', or 'unknown' with respect to the reference. Please note:
First, assess whether the reference contains any valid content. If the reference contains no valid information, such as a 'page not found' message, then all statements should be considered 'unknown'.
If the reference is valid, for a given statement: if the facts or data it contains can be found entirely or partially within the reference, it is considered 'supported' (data accepts rounding); if all facts and data in the statement cannot be found in the reference, it is considered 'unsupported'.

You should return the result in a JSON list format, where each item in the list contains the statement's index and the judgment result, for example:
[
    {
        "idx": 1,
        "result": "supported"
    },
    {
        "idx": 2,
        "result": "unsupported"
    }
]

<statements>
1. Alekseeva, Azar, Giné, Samila and Taska (2021), in Labour Economics, documented a steep rise in employer demand for AI skills over 2010–2019 and estimated a substantial wage premium for such skills within firms and even within job titles.
2. Whether this proves equalizing (as the skill-leveling and Webb's inequality-compression results suggest) or ultimately displacing (as the creative-freelance evidence warns) will depend on how tasks are reorganized and on complementary human skills (Deming, 2017; Alekseeva et al., 2021).
3. Prioritize social, judgment, and adaptive skills that complement machines (Deming, 2017) alongside specialized AI-skill pipelines where the wage premium is highest (Alekseeva et al., 2021).
