An economic analyst is presented with a line chart for a country covering a 25-year period. The chart displays three distinct trends:

1. Economic output per person has consistently increased.
2. Energy use per person for goods produced within the country's borders has generally decreased.
3. A more comprehensive measure of energy use per person, which also includes the energy required to produce imported goods, is consistently higher than the first energy measure but has also shown a general downward trend.

The analyst makes the following claim: 'The persistent gap between the two energy use measures proves that this country has not made genuine environmental progress. It has simply shifted its energy-intensive production to other countries.'

Critically evaluate the analyst's claim based only on the trends described. Is the claim fully supported, partially supported, or largely unsupported by the data? Justify your reasoning by referencing specific trends.
