One such simplification occurs where the subordinated clause '...undermining a long tradition' has been split into a separate sentence. Syntactic simplification often requires discourse preserving edits to maintain the coherence and cohesion of simplified text. For instance, the addition of 'They say...' is necessary to convert the original relative clause into a grammatically correct and coherent sentence.",

However, some work combined lexical simplification with syntactic operations (Coster and Kauchak, 2011; Kauchak, 2013; Zhu et al., 2010) . In recent years simplification has been viewed as a monolingual translation task (Kauchak, 2013; Zhang and Lapata, 2017; Zhu et al., 2010) . These systems perform a number of simplification operations at once by aiming to translate complex English to simple English. Initial approaches attempt this with phrase-based machine translation (Coster and Kauchak, 2011; Wubben et al., 2012) while subsequent work has focused on neural machine translation techniques (Nisioi et al., 2017; Zhang and Lapata, 2017; Shardlow and Nawaz, 2019; Dong et al., 2019) .",

For instance, the work of Rello et al. (2013a) is commonly cited as showing the benefit of text simplification for dyslexic readers. However, this paper demonstrates that the most effective strategy to help dyslexic readers with difficult words, is to provide a range of synonyms for the word, and not to simplify the original. Furthermore, the work of Carroll et al. (1998a) and Carroll et al. (1999a) is put forward as evidence for the utility of simplification for individuals with aphasia. However, both of these works outline the proposal for a simplification system targeted for aphasia and propose to evaluate the effectiveness of such a system in future work. A final example, used in support of text simplification for children is a paper by De Belder and Moens (2010) . However, the paper finds that even using lexical and syntatic simplification, it was not possible to reduce the reading difficulty enough for children.",

In fact, the majority of current work in text simplification is now datadriven and performs simplification in a 'black-box' fashion (Sikka and Mago, 2020) . One of the concerns for such systems, is that they learn operations based on the simplification choices made in the data they are trained with.
