Question

1. As new refugees keep pouring (A)/ dropping (B) in, and those granted asylum have the right to bring family later, there is no end in sight.
2. Schools are struggling to integrate (A)/discipline (B) refugee children who speak no German.
3. While extremist parties have become serious competitors (A)/ contenders (B) for power in some other European countries, they remain marginal in Germany, and voters have faith that their government will restore order. The correct sequence is___

Answer 1

In the first sentence, refugees are coming to a country in mass numbers and hence 'pouring in' is more appropriate in this context. Dropping is not appropriate as refugees do not 'drop in' to a new country.
Schools will face difficulty to 'integrate' the children of refugees in the class who don't speak any German. Disciplining will be a challenge applicable to all children, whether German or others.
Extremist parties are serious 'contenders' for power. A contender has a realistic chance of winning a challenge, a competitor merely competes in the challenge. In this context, the extremist parties are contenders as they have gained considerable support in other European countries.
