High school English, urgent

hello, dear! In these sentences in the picture, their predicate verbs and trunk are as follows:

1. Immigrants are quickly fitting into this common culture which may not be altitogether elevating but is hard poisonous.

subject: Immigrants

predicate verb: are fitting

trunk: immigrants are fitting into this common culture

in this sentence, the trunk refers to the main part of the sentence, generally including the subject and predicate verbs.

In this sentence, immigrants are fitting into this common culture, which means that immigrants are gradually adapting to this same culture.

2. If railroads charged all customers the same average rate they argue shippers who have the option of switching to trucks or other forms of transpo Reaction would do so leaving remaining customers to shoulder the cost of keeping up the line.

Subject: railroads

Predicate verb: argue

Trunk: railroads argue. (Railway Company argues)

In this sentence, unlike the first example, the predicate verb argue of the subject railroads is not the predicate verb of the whole sentence, but a part of the predicate verb of the conditional clause if.

Therefore, this sentence does not have an obvious trunk. It can be understood that the conditional clause if railways charged all customers the same average rate is the backbone of the whole sentence, and the part argued by the railway company is only a clause of the conditional clause.

3. subject: new ways of organizing the workplace-all that re-engineering and downsizing

predicate verb: are

trunk: New ways of organizing the wor. K place is only one contribution to the overall productivity of an economy

4. Subject: The trouble

Predicate verb: is

trunk: The tro. Although it is that part-of the recent acceleration is due to the us rebound (the problem is that part of the recent acceleration is due to the usual rebound in the economic cycle).

I hope I can help you, thank you!
