c. Differences in opinion on how much power the federal government should have.

d. Increase in the distribution of newspapers.

The choices that influenced the emergence of opposing political parties are:

c. Differences in opinion on how much power the federal government should have.
d. Increase in the distribution of newspapers.

To determine which choices influenced the emergence of opposing political parties, let's analyze each option:

a. Looming threat of war with Canada: This option is unlikely to be a factor in the emergence of opposing political parties. Threats of war usually unite people towards a common cause rather than leading to the division of political parties. Therefore, this option can be eliminated.

b. Mounting pressure from Brighton to further establish government: Without additional context, it's difficult to assess the impact of Brighton's pressure on the emergence of opposing political parties. However, if Brighton's pressure is related to conflicting ideas about the role and size of the government, then it could be a contributing factor. We can consider this option plausible for now.

c. Differences in opinion on how much power the federal government should have: This option is highly likely to influence the emergence of opposing political parties. Divisions over the extent of federal government power have historically given rise to ideological differences, leading to the formation of parties with opposing views on governance.

d. Increase in the distribution of newspapers: While an increase in newspaper distribution can contribute to political polarization, it is not necessarily the direct cause of opposing political parties. Newspapers can promote differing opinions and ideas, which can ultimately lead to the formation of political parties. Therefore, this option can also be considered plausible.

In summary, based on our analysis:

- Option a seems unlikely to have influenced the emergence of opposing political parties.
- Options b, c, and d are plausible factors in the emergence of opposing political parties.

Therefore, the correct choices that influenced the emergence of opposing political parties would be: b. Mounting pressure from Brighton to further establish government, c. Differences in opinion on how much power the federal government should have, and d. Increase in the distribution of newspapers.
