I’d say “The Industrial Revolution influenced the theme of injustice and the importance of bravery” hope this helps :)
B if the author can present....
<span>Corruption is stealing of funds that are not supposedly owned by the stealer. In most cases, it mostly happening in institutions and organizations. It is impacting on SA because the taxes that are meant to be allocated on employment projects and policies are stolen.</span>
you have too sight the last name of the author and the page number whether it is a quote or paraphrased. the only time you don't have to is if you include it in the sentence.
Example for when you don't have to cite in text:
On page 13 Martin says, "blah blah bah bluh bleh blah"
... otherwise just put the citation in parentheses after the quote/paraphrase like so: (Martin,13)
