cin>>T;
for(int j=0;j<T;j++){
    cin>>c1>>c2>>c3>>c4>>n>>m;
    int ric[n],cab[m];
    for(i=0;i<n;i++){
        cin>>ric[i];
        if(ric[i]>0)
            r_cost+=min(ric[i]*c1,c2);
    }
    if(r_cost>0)
        cost=min(r_cost,c3);
    for(i=0;i<m;i++){
        cin>>cab[i];
        if(cab[i]>0)
            c_cost+=min(cab[i]*c1,c2);
    }
    if(c_cost>0)
        cost+=min(c_cost,c3);
    cout<<min(cost,c4)<<endl;
