Why are horizontal mergers more likely to affect competition than other types of mergers?

	1.	Mergers do not actually affect competition. The combined companies will have the same amount of competition independently or when combined together.
	2.	Horizontal mergers are the only type of merger and this is why they reduce competition.
	3.	None of the above.
	4.	Horizontal mergers are more likely to affect competition than other types of merger as they are mergers between already competing firms and thus the number of competitors is effectively reduced when one such firm obtains control over another.
	5.	Mergers actually increase competition. They create larger companies and larger companies mean bigger and more competition.
