I start with translating your sentences, hope they make sense. 1)öğlene kadar raftaki deriler neredeyse tükenmişti The magazines that are on the shelf was nearly finished until midday. 2)öğlene kadar raftaki dergiler tükenivermişti The magazines that are on the shelf had been already/quickly finished* until midday. 3)öğlene kadar raftaki dergiler çabucAk tükenmişti The magazines that are on the shelf had been quickly finished until midday. 4)öğlene kadar raftaki dergiler tükenirdi The magazines that are on the shelf used to run out until midday. So the answer is 2 and 3. *When the verb vermek/to give is added to another verb, it means that the verb happens in a shorter time than expected or average.Examples; Beklemediğim bir anda 'Seni seviyorm' deyiverdi. He said I love you (suddenly/unexpectedly). Yola çocuk koşunca, adam aniden arabayı durduruverdi. As a kid run to the road, the man stopped the car suddenly. Actually in all these examples you can use the simple past tense as well (dedi, durdurdu, tükendi) but this form with -vermek is putting some emphasize on how fast it happened.

The apple is red. Elma kırmızı. It is John’s apple. O/Bu John'un elması. I give John the apple. John'a elmayı veriyorum. We give him the apple. Biz ona elmayı veriyoruz. He give it to John. O onu John'a veriyor. She gives it to him. O onu ona veriyor. I don’t give apples. Ben elma vermiyorum.

Yes, your translation is correct. We use the word "en" to make the adjectives superlative just like your example. Some other examples: en büyük - the biggest, en az - the least, en temiz - the cleanest. "En" can mean "width" also. Examples; 1) Bu odanın eni 2 metre. This room's width is 2 meters. 2) Bu masanın eni kaç santimetre? How many centimeters is the width of this table? Umarım yardımcı olabilmişimdir. Çalışmalarınızda başarılar dilerim!

It is the simple past tense and also continuous past tense suffix for the subject "we". We use the same suffix to say 'we used to do something'- something that we used to do in the past repeatedly. Another use is 'we had done something', past perfect tense in English. Also to say 'we were going to do something' again we use this suffix. It can be dık, dik, duk, dük. We decide which one to choose (ı,i,u,ü) looking at the the last vowel of the verb. If the last vowel a,ı --> dık, e,i --> dik, o,u --> duk, ö,ü --> dük. Before we add this suffix, if the last consonant is one of these letters f,s,t,k,ç,ş,h,p then the letter d turns into t and the suffix becomes; tık, tik, tuk, tük instead. Some examples with their translations; (biz: we, ev: home, -e: to, gelmek: to come, doktor: doctor) Biz doktorduk. We were doctors. Biz eve geldik. We came home. Biz eve geliyorduk. We were coming home. Biz eve gelirdik. We used to come home. Biz eve gelmiştik. We had come home. Biz eve gelecektik. We were going to come home. -->We can use it when we use 'could' or 'would' in the past tense, too. Biz eve gelebilirdik. We could/would come home.

--> It can create adjectives (If a vowel comes after k turns into ğ and it becomes dığ, diğ, duğ, düğ). This is same as noun but the difference is that this one is followed by a noun.)It is same for the present and the past tense. We understand the time from the rest of the sentence or the conversation. gördüğüm ev - the house that I see/saw okuduğumuz kitap - the book that we have read/read --> It can create an adverbial (In this case it is same for all subjects and also tenses) (Biz) Yedikten sonra koşacağız. We will run after we eat. (Ben) Seni gördükten sonra eve gittim. I went home after I saw you. (Sen) Benimle konuştuktan sonra ne yaptın? What have you done after you talked to me? (Biz) Geldiğimizde onlar çoktan gitmişti. When we came, they were already gone. --> As a noun Sevdiklerimiz burada yanımızdalar. Our beloved ones are here with us. (Sen) Anlattıklarımı dinledin mi? Have you listened to what I told you? (Ben) Okuduklarımı anladım. I understood what I read. Some other examples; Biz gönüllüydük. We were volunteers. Biz anladık. We understood. Biz uyuyorduk. We were sleeping. Biz yüzerdik. We used to swim. Biz yazmıştık. We had written. Biz okuyacaktık. We were going to read. Biz yardım edebilirdik. We could/would help.

Karar vermek gerçekten çok zor ama sanırım "içli köfte". Şiş kebap, yaprak sarması, lahmacun ve döner de gayet şahane.

hangi doğru? must be "hangisi doğru?" İkisi de doğru. (Bu cümlede de ayrı yazılır, çünkü İngilizce'deki also,too kelimesinin karşılığıdır. -de eki İngilizce in,on,at anlamında kullanıldığı zaman bitişik yazılır. Fakat her nedense Türklerin çoğu her zaman bitişik yazar, "also" anlamında olsa bile.)
