Part I:
If you practised more, your english would improve.If I had a motorbike, it would be easier to go and visit my friends.If I lost all my money, I would feel miserableIf I started writing poetry, My English teacher would be surprised.If Peter ate less, he wouldn't be so fat.If my little sister did something wrong, I'm sure she'd tell meIf I were a famous model, people would see my photo everywhere.
Part II:
I didn't wait another minute. I didn't see you.I didn't wait another minute because I didn't see you
Explanation for Part I:
As the quote says, "Practice makes Perfect", [which is not true, but it does improve your ability to do such tasks]. The only one choice that has anything to do with practicing would be english, so "your english would improve." is your answerThe sentence is talking about "visiting friends" which should mean that you must "travel" there. The only answer choice would be "If I had a motorbike...", because it is the only transportation answer choice there is.While you can feel miserable in many scenarios, "If I lost all my money" would be the only choice that would work out of the choices given to you, for it is the only inherently negative answer choice.Poetry is encompassed within the realm of the subject English, and so there can only be two choices: "your English would improve" and "my English teacher would be surprised". Since the sentence used "I", and not "you", "my English teacher would be surprised" is your answer choice.Being "fat" would obviously cause a negative reaction, and would be the effect of doing something negative. Being fat generally comes from overeating, and so "If Peter ate less" is your best choice. Also, note that  it is masculine (Note: He), and so "If Peter ate less" is your answer choice."I'm Sure she'd tell me" is the only answer choice for this regardless of if you did it out of order or not, because "sister" is a feminine term, in which you would use a feminine pronoun, or in this case, "She'd"."If I were a famous model", is the only one that works in here, because photo circulation generally only happens for famous people.
Explanation for Part II:
Essentially, what it is asking you to do is to combine the sentence, but to also "keep it's meaning" (still make sense). The sentences given to you really means that the writer didn't wait because he didn't see his recipient, so your answer in combining is: "I didn't wait another minute because I didn't see you.", putting the action behind the reason.
