A.I. Explanation:

Option 1: "encouraged workers to demand higher wages"

Explanation: This option is incorrect because the text does not mention that political party loyalties or disagreements over tactics encouraged workers to demand higher wages. Instead, the focus is on the divisions among workers rather than their collective demands.

Option 2: "created divisions among workers"

Explanation: This option is correct as the text explicitly states that workers were divided by various factors, including political party loyalties and disagreements over tactics. This division is a central theme in the text, highlighting how these factors contributed to a lack of unity among workers.

Option 3: "caused work to become more specialized"

Explanation: This option is incorrect because the text does not discuss specialization of work as a result of political party loyalties or disagreements over tactics. The focus is on the divisions and resentments rather than changes in work specialization.

Option 4: "increased workers’ resentment of the industrial system"

Explanation: This option is incorrect as the text indicates that workers resented the industrial system, but it does not link this resentment directly to political party loyalties or disagreements over tactics. The resentment is presented as a general sentiment rather than a result of these specific factors.
