    "hint": "Which preposition do we use with days of the week, like Monday or Friday?",
    "explanation": "Days of the week take the preposition “on”: on Wednesday, on Friday, on Monday morning. English uses three prepositions of time in a general-to-specific pattern: “in” for long periods (in July, in 2015), “on” for days and dates, and “at” for exact clock times (at 9 o’clock). Wednesday is a single day, so “The test is on Wednesday” is correct; “in Wednesday” and “at Wednesday” are common learner mistakes."

    "hint": "A date is a particular day. Which preposition goes with days?",
    "explanation": "A date such as 2nd May names one particular day, so it follows the same rule as days of the week and takes “on”: on 2nd May, on 4th July, on my birthday. Be careful: the month alone is a longer period and takes “in” (in May), but as soon as you add the day number, the preposition changes to “on”. “At” is only for clock times (at 7 p.m.)."

    "hint": "Is July a single day or a longer period of time?",
    "explanation": "Months, seasons and years are long periods, and long periods take “in”: in July, in summer, in 2024. “On” is used only for days and dates (on 1st July), and “at” is for exact times (at noon). So the holidays start in July. A useful memory aid: the longer the period, the more “inside” it you are — in a month, in a year, in a century."

    "arabic": "هل وُلد أخوك ___ عام ٢٠١٥؟",
    "hint": "A year is a long period, like a month. Which preposition do we use with long periods?",
    "explanation": "Years are long periods, so we use “in”: born in 2015, the Olympics in 1964. This is the same rule as for months (in March) and seasons (in winter). “On” would need a specific day (born on 3rd June 2015), and “at” is for clock times. So the question is “Was your brother born in 2015?”."

    "explanation": "In “My idea is to have a dinner party”, the word “to” is the infinitive marker, so it must be followed by the base form of the verb (to have, to go, to visit). “Has” is a present-simple form and “having” is an -ing form; neither can follow the infinitive “to”. Be careful not to over-generalize: when “to” is a preposition, as in “I look forward to meeting you” or “I’m used to working late”, it is followed by an -ing form or a noun, not a base verb."

    "explanation": "“Why don’t we …?” is a common way to make a suggestion (Unit 2A). Because it contains the auxiliary “don’t”, it is followed by the base form of the verb: Why don’t we go to a restaurant? Why don’t we invite Sara? “Goes” has the third-person -s, which is never used after an auxiliary, and “going” is used after “How about …?”, not after “Why don’t we …?”."

    "hint": "“Could” is a modal verb. What form of the main verb follows modal verbs?",
    "explanation": "“We could …” is another way to make a suggestion. “Could” is a modal verb, and modal verbs (can, could, should, must …) are always followed by the base form without “to”: We could see a play; You should rest. “Saw” is a past form and “seeing” is an -ing form, so neither can follow a modal.

    "hint": "In suggestions, “How about” works like a preposition. What verb form follows prepositions?",
    "explanation": "“How about …?” and “What about …?” are suggestion phrases that end in a preposition (“about”). After a preposition, a verb must take the -ing form: How about organizing a picnic? What about going to the beach? You can also use a noun: How about a picnic? “Organize” (base form) is used after “Why don’t we …?” or “Let’s …”, and “organizes” is a present-simple form that does not fit here."

The form of “be” must agree with the subject: I am, he/she/it is, you/we/they are.

Short adjectives add -er (cheap → cheaper), but adjectives of two or more syllables usually use “more”: expensive → more expensive, comfortable → more comfortable.

    "explanation": "“Ever recorded” compares these years with all other years, so we need the superlative. One-syllable adjectives form the superlative with -est, and if they end in one vowel + one consonant, the final consonant doubles: hot → the hottest, big → the biggest, thin → the thinnest. “The hotest” forgets to double the t, and “the most hot” is wrong because “most” is used only with longer adjectives."

    "explanation": "“Slim” means thin in an attractive, healthy way (Unit 3A also uses it for thin devices). Tight trousers fit only a slim person, so: Noor is not slim enough to wear these tight trousers.

    "explanation": "When a verb ends in a vowel + y (stay, play, enjoy), we simply add -ed: stayed, played, enjoyed. We change y to i only when there is a consonant before the y (study → studied, try → tried). So “staied” is a spelling mistake. “Last week” requires the past simple, so “stay” and “staying” are also wrong."

    "explanation": "“Retire” means to stop working, usually because you have reached a certain age: She retired from the bank last year. The preposition “from” + workplace is a common pattern (retire from the army). “Stood”, “repaired” and “drew” do not have this meaning."

    "hint": "Classify each adjective: is it an opinion, an age, or a place of origin?",
    "explanation": "The answer is True. When several adjectives come before a noun, English usually follows this order: opinion → size → age → shape → colour → origin → material → noun (Writing skills, Unit 4). In “a lovely old Italian bed”, “lovely” is an opinion, “old” is age and “Italian” is origin, so the order is correct. Another example: a beautiful small round wooden table."

To “fail an exam” means not to pass it: My friend failed his exams, which explains his sadness. “Passed” is the opposite and would make him happy; you do not “win” an exam (you win a game or a prize), and “broke” does not collocate with “exams”."

    "explanation": "“Time” is uncountable, so we need a quantifier for uncountable nouns. “Little” (without “a”) means “not much, not enough” and has a negative meaning: She has little time to spare. Compare “a little time”, which means “some time”. “Many” and “fewer” are for countable nouns, and “any” is not normally used in a positive statement like this."

Changing this order usually makes the sentence wrong or changes it into another type: questions put an auxiliary before the subject (Does Ali read books?), and commands start with the verb (Read the book!)."

An object must be a noun or pronoun that receives the action of a verb, as in “She reads a book”. Words that follow “be” and describe the subject are called complements, not objects."

    "hint": "Which noun is something bad in the air of a city?",
    "explanation": "“Pollution” is uncountable, so it fits “a lot of ___”, and it describes something harmful in the city’s air or water. “Population” is the number of people, which we describe as “large”, not “a lot of population”, and “develop” is a verb, so it cannot follow “a lot of”."
