❇️Analysis of the answers:

1. lag : The word “will” is a modal verb and modal verbs cannot be used on their own. After a modal verb, the root form of a verb is generally used. Based on the meaning, “lag” is the right verb.
2. dissected : The sentence lacks a verb and after the base form of to-be “be” the past participle form of the main verb is used. Based on the meaning and tense “dissected” is the right verb. Extra tip: Modal verbs + be + past participle
3. canard : After the definite article “the” and a noun is used and based on the meaning of the word “canard”, it is the right noun.
4. competitiveness: A coordinating conjunction such as “and” is a word that joins two elements of equal grammatical rank and syntactic importance and therefore they can join two verbs, two nouns, two adjectives, two phrases, or two independent clauses. Since “attraction” is a noun, the word that precedes the conjunction “and” is also a noun. Based on the meaning the right noun is “competitiveness”.
5. lucrative : Attributive adjective is an adjective that usually comes before the noun it modifies without a linking verb. The word “offers” as a noun is preceded and described by an adjective “lucrative”. Based on the meaning, “lucrative” is the right adjective.

۱. واژه “will” یک modal verb است و آنها نمی توانند به تنهایی استفاده شوند. بعد از یک modal verb، بطورکلی شکل اصلی فعل استفاده می شود. براساس معنا، فعل صحیح “lag” می باشد.
۲. جمله فاقد فعل می باشد و بعد از شکل اصلی to-be که “be” می باشد شکل سوم (past participle) فعل اصلی استفاده شده است. براساس معنا و زمان، فعل صحیح “dissected” می باشد. نکته: modal verb + be + past participle
۳. بعد از حرف تعریف معین “the” از یک اسم (noun) استفاده شده است. بر اساس معنای لغت “canard” پاسخ صحیح است.
۴. حرف ربط همپایه (coordinating conjunction) مانند ‘and’ کلمه ای است که دو عنصر از درجه دستوری برابر و اهمیت نحوی را پیوند می زند و بنابراین می توانند دو فعل، دو اسم، دو صفت، دو عبارت یا دو بند را بهم متصل کنند. از آنجایی که “attraction” یک اسم است، کلمه ای که قبل از حرف ربط همپایه (conjunction) ‘and’ آمده است نیز اسم می باشد. براساس معنا، اسم صحیح “competitiveness” می باشد.
۵. 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 “offers” به عنوان اسم (noun) در ادامه یک صفت که “lucrative” می باشد آمده و توسط اش توصیف شده است. براساس معنا، صفت صحیح “lucrative” می باشد.

#RFIB_Answer_263

❇️Analysis of the answers:

1. reattaching : If we want to use a verb after a preposition, it must be in –ing form. It is impossible to use an infinitive after a preposition. This form of verbs are called “gerund”, “gerund” is a form that is derived from a verb but that functions as a noun. Based on the structure, “reattaching” is the right answer.
2. flow : After the infinitive maker “to” the base form of the verb is used and based on the meaning, “flow” is the right verb.
3. delicate : Attributive adjective is an adjective that usually comes before the noun it modifies without a linking verb. The word “procedure” as a noun is preceded and described by an adjective “delicate”. Based on the meaning, “delicate” is the right adjective.
4. performed : 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, “performed” is the right answer.
5. obstruction: A compound noun contains two or more words that join together to make a single noun, like “air obstruction”. Some compound nouns function as one unique word, but are still written as two or more separate words. The second part of the compound noun identifies the object or person being described by the first part. Based on the meaning “obstruction” is the right answer.

❇️تحلیل»

۱. اگر بخواهیم بعد از یک حرف اضافه از یک فعل استفاده کنیم، باید شکل –ing فعل باشد. استفاده از مصدر فعل (infinitive) بعد از حرف اضافه غیرممکن است. این شکل از فعل “gerund” نامیده می شوند، “gerund” فرمی است که از فعل ناشی می شود ولی به عنوان یک اسم (noun) عمل می کند. براساس ساختار، پاسخ صحیح “reattaching” می باشد.
۲. بعد از مصدر ساز ‘to’ یک فعل در شکل اصلی اش استفاده می شود و براساس معنا، فعل صحیح “flow” می باشد.
۳. 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 “procedure” به عنوان اسم (noun) در ادامه یک صفت که “delicate” می باشد آمده و توسط اش توصیف شده است. براساس معنا، صفت صحیح “delicate” می باشد.
۴. 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،“performed” پاسخ صحیح است.
۵. اسم مرکب (compound noun) اسمی است که از دو یا چند کلمه تشکیل شده که برای ساختن یک اسم (noun) واحد به هم می پیوندند، مانند “air obstruction”. بعضی از اسم های مرکب کارکرد یک واژه منحصربفرد را دارند اما همچنان به عنوان دو کلمه و یا بیشتر جداگانه نوشته میشوند. قسمت دوم موضوع یا شخص مورد نظر که توسط قسمت اول توصیف شده است را مشخص می کند. براساس معنا، پاسخ صحیح “obstruction” می باشد.

❇️Analysis of the answers:

5. relatively (adv.) : in relation, comparison, or proportion to something else.بطور نسبی

#RFIB_Answer_New184

❇️Analysis of the answers:

1. adornment : Since the Adjective’s main function is to describe and modify nouns, “Personal” as an adjective is followed by the noun it modifies. Based on the meaning, the right noun is “adornment”.
2. include : The sentence lacks a main verb and based on the subject-verb agreement principles, “items” as the plural subject of the sentence demands a plural verb. Based on the subject-verb agreement principles and the meaning, “include” is the right answer.
3. fertility : A compound noun contains two or more words that join together to make a single noun, like “fertility problems”. Some compound nouns function as one unique word, but are still written as two or more separate words. The second part of the compound noun identifies the object or person being described by the first part. Based on the meaning “fertility” is the right answer.

3. اسم مرکب compound noun اسمی است که از دو یا چند کلمه تشکیل شده است که برای ساختن یک اسم noun واحد جمع می شوند، مانند “fertility problems”. بعضی از اسم های مرکب کارکرد یک واژه منحصربفرد را دارند اما همچنان به عنوان دو کلمه و یا بیشتر جداگانه نوشته میشوند. قسمت دوم موضوع یا شخص مورد نظر که توسط قسمت اول توصیف شده است را مشخص می کند. براساس معنا پاسخ صحیح “fertility” می باشد.

3. diversity (n.) : the fact of many different types of things or people being included in something; a range of different things or people. تنوع – گوناگونی
4. indigenous (adj.) : originating or occurring naturally in a particular place; native.بومی
5. dispersed (v.) : distribute or spread over a wide area.متفرق شدن – پراکنده کردن

#RFIB_Answer_New166

❇️Analysis of the answers:

1. diametrically : The word “opposed” as the adjective is preceded and modified by an adverb and based on the meaning “diametrically” is the right adverb.
2. proposed : Based on the auxiliary verb “have been”, lack of subject and the absence of the main verb in this sentence, it is obvious to us that the voice of the sentence is passive. In the present perfect tense we make passive verb forms by putting has/have + been before the past participle form of the verb. Based on the structure and meaning, “proposed” is the right answer.
3. diversity : A compound noun contains two or more words that join together to make a single noun, like “coconut diversity”. Some compound nouns function as one unique word, but are still written as two or more separate words. The second part of the compound noun identifies the object or person being described by the first part. Based on the meaning “diversity” is the right answer.
4. indigenous : Adjectives are usually placed before the nouns they modify, but when used with linking verbs, such as the different forms of to-be or sense verbs, they are placed after the verb. This type of verb links the subject of the sentence with an adjective or noun. These adjectives are called predicative adjectives. After the linking verb “are” an adjective can be placed. Based on the meaning, the right adjective is “indigenous”.
5. dispersed : The subject of the sentence is unknown and it is concluded that the sentence has a passive voice. The past simple passive is formed by using 'was' or 'were' plus the past participle. Based on the meaning and the tense “dispersed” is the right answer.

❇️تحلیل»

1. واژه “opposed” به عنوان صفت در ادامه یک قید (adverb) آمده و توصیف شده توسط آن است و براساس معنا، قید صحیح “diametrically” می باشد.
2. براساس فعل کمکی (auxiliary verb) ‘have been’، فقدان فاعل و عدم وجود فعل اصلی در این جمله، بدیهی است که این یک جمله passive است. در زمان present perfect ساختار passive با قرار دادن has/have + been قبل از past participle (شکل سوم فعل) ساخته می شود. براساس ساختار و معنا، واژه “proposed” پاسخ صحیح می باشد.
3. اسم مرکب compound noun اسمی است که از دو یا چند کلمه تشکیل شده است که برای ساختن یک اسم noun واحد جمع می شوند، مانند “coconut diversity”. بعضی از اسم های مرکب کارکرد یک واژه منحصربفرد را دارند اما همچنان به عنوان دو کلمه و یا بیشتر جداگانه نوشته میشوند. قسمت دوم موضوع یا شخص مورد نظر که توسط قسمت اول توصیف شده است را مشخص می کند. براساس معنا پاسخ صحیح “diversity” می باشد.
4. صفت ها معمولاً قبل از اسمی (noun) که توصیف می کنند قرار می گیرند، اما وقتی با فعل ربط (linking verbs) همانند شکل های مختلف فعل to-be یا فعل های sense استفاده شوند، بعد از فعل قرار می گیرند. این گونه از فعل، فاعل را به صفت یا اسم مرتبط و متصل می کند. این صفت ها predicative adjectives نامیده می شوند. بعد از فعل ربط “are” یک صفت می تواند قرار گیرد. براساس معنا، صفت صحیح “indigenous” می باشد.
5. فاعل جمله نامشخص است و در نتیجه جمله مجهول است. ساختار past simple passive بااستفاده از was/were به اضافه past participle تشکیل می شود. براساس معنا، پاسخ صحیح “dispersed” می باشد.
