I'm not clear on what you mean by "(= a plural)"

Thanks

I'm very confused by the explanation regarding the use of indirect and direct object pronouns with hacer + infinitive. The lesson says that indirect object pronouns are used with intransitive verbs, but shows direct object pronouns (lo) with the intransitive verb "arrodillarse". The lesson then says that direct object pronouns are used with transitive verbs, but then shows indirect object pronouns (les) with the transitive verb "pedir (pardón)". Is this a mistake, or am I misunderstanding?

I'm also confused by the difference between the example in the lesson and the example sentence further below:

The lesson teaches: 
Les ha hecho pedir perdón al profesor"
He made them apologise to the teacher.

But the examples sentences below show:

Los ha hecho pedir perdón al profesor.He made them apologise to the teacher.
I am completely confused :(
