Here's one way
awk 'for(a=2;a<=NF;a++)printf "%s %s%cn",$1,$a,a==NF ? "" : ";"' File.txt >File_2_Columns.txt
Good luck with the rest of your homework ;-)
If teacher is giving extra credits for shortest answer, try
awk 'for(a=2;a<=NF;)printf"%s%cn",$1" "$a,a++-NF?";":""' File.txt >File_2_Columns.txt
