+    This, however, is rarely applicable for low-resource languages where traditional handcrafted features are still \
+    widely used due to the lack of existing NLP tools to extract deeper linguistic representations. In this work, \
+    we take a step back from the technical component and focus on how linguistic aspects such as mutual intelligibility \
+    or degree of language relatedness can improve ARA in a low-resource setting. We collect short stories written in three \
+    languages in the Philippines{---}Tagalog, Bikol, and Cebuano{---}to train readability assessment models and explore the \
+    interaction of data and features in various cross-lingual setups. Our results show that the inclusion of CrossNGO, \
+    a novel specialized feature exploiting n-gram overlap applied to languages with high mutual intelligibility, \
+    significantly improves the performance of ARA models compared to the use of off-the-shelf large multilingual \
+    language models alone. Consequently, when both linguistic representations are combined, we achieve state-of-the-art \
+    results for Tagalog and Cebuano, and baseline scores for ARA in Bikol.",
