Definition: Rewrite each original sentence in order to make it easier to understand by non-native speakers of English. You can do so by replacing complex words with simpler synonyms (i.e. paraphrasing), deleting unimportant information (i.e. compression), and/or splitting a long complex sentence into several simpler ones. The final simplified sentences need to be grammatical, fluent, and retain the main ideas of their original counterparts without altering their meanings.
Input: Given these assumptions it is possible to calculate how often they can fail and to arrange the array to make data loss arbitrarily improbable.

We are able to calculate how often they can fail and to arrange the array to make data loss arbitrarily improbable.
