The answers are 1a and 2b:
1) (CAT)5, as (CATCAT) can be broken down into two smaller motifs.
2) (AAAGTC)3, as the motifs must be continuous.
Of course, if the thresholds were set to detect mono repeats of such a small size then we would indeed find (AAA)3 and (GTC)3, but I usually don't run thresholds that low as such things are not biologically significant. Generally, if it's over about 10 repeats of the pattern it might be interesting, or about 20 repeats if it's a single character. Sorry for the vagueness on this matter.
