❇️Analysis of the answers:

1. classified : In the present simple, the passive is: am / is / are + past participle (3rd form of the verb). The Sentence lacks a subject and has the structure of the passive voice. Based on the meaning and the tense, “classified” is the right answer.
2. perioperative : Attributive adjective is an adjective that usually comes before the noun it modifies without a linking verb. The word “physicians” as noun is preceded and described by an adjective “perioperative”. Based on the meaning, “perioperative” is the right adjective.
3. experts : A determiner is a word that introduces a noun. It always comes before a noun, not after, and it also comes before any other adjectives used to describe the noun. The word “these” as a determiner, used mainly for plural nouns, is followed by a plural noun. Based on the meaning, the right noun is “experts”.
4. administer : After the infinitive maker “to” the base form of the verb is used and based on the meaning, “administer” is the right verb.
5. state : Since the Adjective’s main function is to describe and modify nouns, “temporary” as an adjective is followed by the noun it modifies. Based on the meaning, the right noun is “state”.

1. ساختار جمله مجهول در حال ساده (present simple - passive) برابر است با: am/is/are + past participle. جمله فاقد فاعل (subject) است و ساختار مجهول (passive) دارد. براساس معنا و زمان فعل،“classified” پاسخ صحیح است.
2. یک attributive adjective، صفتی است که معمولاً قبل از اسمی (noun) که توصیف می کند و بدون یک فعل ربط (linking verb) می آید. واژه “physicians” به عنوان اسم (noun) در ادامه یک صفت که “perioperative” می باشد آمده و توسط اش توصیف شده است. براساس معنا، صفت صحیح “perioperative” می باشد.
3. یک تعیین کننده یا پیشرو اسم (determiner) واژه ای است که یک اسم (noun) را معرفی می کند. تعیین کننده ها همیشه قبل از اسم می آیند و نه بعد، و قبل از هر صفتی که برای توصیف اسم استفاده شده است می آیند. واژه “these” به عنوان یک determiner،(بطورکلی برای اسم های جمع استفاده می شود)، با یک اسم جمع (plural noun) ادامه یافته است.براساس معنا و ساختار، اسم صحیح “experts” می باشد.
4. بعد از مصدر ساز ‘to’ یک فعل در شکل اصلی اش استفاده می شود و براساس معنا، فعل صحیح “administer” می باشد.
5. از آنجایی که کارکرد اصلی صفت توصیف و اصلاح اسم (noun) می باشد، واژه “temporary” به عنوان یک صفت با یک اسم که آن را توصیف می کند ادامه یافته است. براساس معنا، اسم صحیح “state” می باشد.
