解析:该题为细节题,通过题干petitions(请愿书)和campaigners(运动领导者)进行定位。通过campaigners所在句子"The
RHS'sdecision comes as campaigners try to raise awareness of the problems fake grass causes."得知,campaigners试图提高人们对假草造成的问题的认识。下文
petitions所在句子,详细说明提升对假草问题的具体方式:It is trying to encourage people to sign two petitions,one calling for a ban on the sale of plastic grass and
another calling for an"ecological damage"taxon such lawns.即"呼吁禁止销售塑料草,和呼吁对此类草坪征收"生态破坏"税"。只有B选项resistance to fake grass use(对假草使用的抵制),对定位句进行了同义改写。
