In yesterday' s council election a majority of voters supported conservative candidates, and a majority of voters supported candidates who voted in favor of the antipollution act
Bill claims that soil can be damaged if it is tilled when it is too wet, and Sue claims that seeds planted in wet soil can rot. Ttherefore, if both claims are true, gardeners who till and plant their gardens when the soil is wet damage both their soil and their seeds.
