× Significant difference among the mean of antithesis arguments of
texts B and A, p = 0,002<0,017
† Significant difference among the mean of antithesis arguments of
texts C and A, p = 0,001<0,017

The difference of cause and effect arguments was significant among
texts Β and Α (p = 0,001 < 0,017) and among texts C and Α (p = 0,000
< 0,017), while the difference among the texts B and C was not statisti-
cally significant (p = 0,193 > 0,017). Also, the increase of antithesis ar-
guments was statistically significant among texts A and B (p = 0,002 <
0,017) and among texts A and C (p = ,001 < 0,017), but not among the
texts B and C (p = ,894 > 0,017). When it comes to the arguments based
on the sub-topic of antecedent and consequent, a significant difference
was noticed only between the initial Text A (M = 0,13) and the final
Text C (M = 0,57) (p = 0,013 < 0,017) in favour of the final text (Text C).
On the contrary, no significant difference concerning the production of
arguments based on the sub-topic of similarity and the subtopic of dif-
ference was noticed.

texts A, B and C
Furthermore, the statistical analysis showed a significant increase of
the mean of stylistic elements (M = 0,4783, SD = 0,51075: Text A, M =
1,6087, SD = 1,49967: Text B and M = 1,2609, SD = 1,05388: Text C). A
statistically important difference was noticed among texts A and B (p =
0,003<0,017) and among texts A and C (p = 0,004 < 0,017), while there
was no important difference among texts B and C.
The mean of rhetorical questions, to complete the one-way repeat-
ed-measures ANOVA, varied from M = 0,13 (SD = 0,344: Text A), to M
= 1,17 (SD = 1,154: Text B) and to M = 1,04 (SD = 0,976: Text C) (Figure
