need help explaining old LG... Forum

[xqhp82]

I was working on these older games from PT1-20 that I have faced some troubles but wasn't able to solve them myself. would be grateful if anyone of you here can make things clearer for me..im so completely clueless especially the last 2

PT5 LG#1 (need advice on effective diagramming)

PT 15 LG #3

PT 4 LG #3 (need help explaining answers)

PT 17 LG #3

PT 19 LG #2

is it just me or are they rather difficult questions? I have only just gone through Advanced Linear section in LGB and it doesn't seem to mention tactics to deal with any of the above problems.

thanks!
