The Arboretum Curie, also known as the Arboretum du Col des Trois Soeurs, is a small arboretum located at 1470 metres altitude in the Col des Trois Soeurs near La Panouse, Lozère, Languedoc-Roussillon, France. It was created circa 1975 to study conifers suitable for reforestation, and according to Arbez et al., now contains 77 taxa (primarily conifers).
Conifers are the main staple of the Arboretum and are the reason for which it was built.
My statement belongs to this category because, based on the context, it is providing a fact. I believe that the system found it difficult because I simply generalized what the context was saying without using any numbers.
