A The verb phrase “generations that will be born” (lines 3 and 4), would be incorrect if the verb “be” were omitted.
B In lines 1 and 2, the words “weak” and “strong” could be correctly written in the plural form, as in “weaks” and “strongs”.
C The verb phrase “What is worth it in life” (line 4) would remain correct if the pronoun “it” were omitted.
D The phrase “in the end” (line 5) could be written as “at the end” without change in meaning.
E The phrase “you will be able to reap what you sowed” (line 6) could be correctly shortened as “you will have what to reap”.
