Fragile ecosystems like the Arctic could face many more years of contamination from PCBs (polychlorinated biphenyls), despite international treaties banning their use. ----. An estimated 1.3 million tonnes of PCBs were made between the 1930s and 1990s around the world for use in the manufacture of pesticides, lubricants, and plastics. But an investigation to determine the fate of these PCBs has failed to locate most of them.

A) On the other hand, PCBs may be carried by wind to cold countries where they condense out in the cold air
B) Indeed, soils in temperate lands have captured most of the PCBs so far released into the environment
C) On the contrary, PCBs could pose a threat to polar bears for years to come
D) That is the conclusion of a study into the fate of PCBs manufactured worldwide during much of the 20th century
E) As a result, urban air contains more PCBs than rural air

Şurdan git istersen kardeş:) .... dan sonra cümle past olarak devam ediyor, boşluğa present gelebilir mi ?
That is the conclusion of a study into the fate of PCBs manufactured worldwide during much of the 20th century

c sıkkı olmaz cünkü zaten bastan bir cok tehlike yaratabileceğini söylüyor yasaklanmasına ragmen csıkkını koyunca da on the contrary aksi bir durumdan söz ediyor ve yine zararlarından bir tane bahsediyor aksi durum olunca iyi bir şeyin olması gerekmez miydi

artcıya katılıyorum bende d sıkkı diyorum manufactured bi kere o olay anının vermiş zaten

manufactured ..... Verb mü ?

evet bence verb manufacture=üretmek

evet bence verb manufacture=üretmek

Bence verb değil.:) Orada relative Clause reduction var... ayrıca passive... imal edilmiş anlamında.Cümlenin verb'i is....

olabilir tabi ama dedigim gibi c sıkkı olmaz on the contrary den dolayı ama bi de d sıkkında 20.yüzyıl var bence diger cümleyide karsılıyor

Bence verb değil.:) Orada relative Clause reduction var... ayrıca passive... imal edilmiş anlamında.Cümlenin verb'i is....

Ve yine ayrıca cevabınıza katılıyorum.:D haklısınız on the contrary bozuyor.D seçeneği present olmasına karşın önceki ifadeyi destekliyor.

Ahhh doğrumu yapmışımm teşekkürler teşekkürler bekle üds ben geliyorumm:))

D seçeneği doğru seçenekti. 'That' ile bir önceki cümlede yer alan ifadeye atıfta bulunulmuş, devam eden kısmın açıklaması bir sonraki cümlede mavi ile renklendirilmiş kısımda detaylandırılarak verilmiş.

Bu tarz sorualara ilişkin açıklamalı bir dosya ekledim şuraya (http://www.dilforum.com/forum/showthread.php?p=171179#post171179), faydalı olacaktır.

bu soruyu cevap şıklarını hiç okumadan, sadece despite tan sonra gelen cümlenin bi bağlaç veya türevi cümleyle başlamayacağını göz önüne alarak yaptım. Bu yol doğru mu?
