Answer:
The answers are: 
- You don't trust her/him anymore. 
- You can't agree anymore never on anything. 
Explanation:
Two possible examples that one can identify when there are these two relationship problems are: Constantly revising her/his cellphone secretely (while she/he is taking a shower, leaves cell phone, etc...) And constant discussions for simple or serious issues in front of other people. 
What the couple can do is firstly to sit down and tell to each other what is bothering each of them, for instance, "the cellphone" problem, perhaps one of them is using the cellphone more than usual, and well if there is no communication as to say " oh honey, look, my friends sent me this funny picture" or, "omg, my boss wants me to go to work on Sunday", or "I have so much work, darling, I have to attend several messages/calls"... perhaps that could do a big difference. And with regards to the other issue, well, it's just a matter of establishing priorities, again, sit down and talk... 
 
        
             
        
        
        
Answer:
Number 4 would be the best answer.
Explanation:
Passing through each option, from a deductible, logical perspective: 
- Number 3 cannot be concluded from the excerpt given.
- Number 1  could maybe be a possible answer, but can be dropped aside due to the fact that the speaker implies a certain level of pride to his statement, when he says that he has made the railroad 'race against time'. Hence, he would probably still want to keep building them!
- Number 2 is the one that is maybe best confused. As the conclusion 'Now it's done!' could very much either mean that all railroads have been completed, or that he hasn't found work anymore. This can be clarified by considering that he's talking about <em>a </em><em>railroad, </em>and that his whole speech has a certain emotional, almost poethical appeal to it. So the main point here isn't the general need for railroads, but rather the speaker's feelings and aflictions.
