A2 Key for Schools (KET) Reading & Writing Part 5 Test – Tech Recommendations: Suggesting Apps, Games & Content 7

25 a

– Why it's right: We use the word "a" before a singular describing phrase (brilliant tablet) when we mention what kind of thing it is for the first time.

– Why not 'the': We cannot use "the" here because Oliver is just describing the tablet generally, not talking about one specific tablet that Jack already knows about.

26 on

– Why it's right: We use the preposition "on" when we talk about things hitting or resting on a flat surface, like a floor, table, or wall.

– Why not 'in': We cannot say "in the floor" because the tablet hit the top surface of the ground, it did not go inside it.

27 because

– Why it's right: We use the conjunction "because" to explain the reason for a feeling or action. It answers why Oliver was scared.

– Why not 'so': "So" introduces a result, but thinking the screen was broken is the reason he was scared, not the result of being scared.

28 There

– Why it's right: We use the word "There" together with the verb "are" to introduce things that exist in a place (There are lots of cases).

– Why not 'They': A common mistake is writing "They are lots of cases", but "they" is a personal pronoun used to replace a noun, not to introduce a new fact.

29 me

– Why it's right: We need the object pronoun "me" because it receives the action of the verb "want". The phrase "want me to [do something]" is very common.

– Why not 'I': We cannot write "want I to send" because "I" is a subject pronoun and is only used at the beginning of a clause, never directly after an action verb.

30 are

– Why it's right: We need the auxiliary verb "are" to match the plural pronoun "We" and complete the future plan structure "are going to".

– Why not 'will': While "will" also talks about the future, we cannot say "We will going" because "will" is never followed directly by an -ing word.

25 of

– Why it's right: We use of in the fixed phrase lots of (or a lot of) to talk about a large number of things.

– Why not 'for': We cannot say lots for; the correct preposition to complete this quantity phrase is always of.

26 because

– Why it's right: We use because to give a reason for something (the videos are interesting because they use animations).

– Why not 'so': We use so to talk about the result of a situation, but here Ella is explaining the reason why she likes the videos.

27 the

– Why it's right: We always use the definite article the before superlative adjectives like best, biggest, or fastest.

– Why not 'a': We cannot use a because there is only one best channel in this context, not many.

28 going

– Why it's right: We use going after the verb am and before to when we talk about a future plan or intention (am going to send).

– Why not 'go': We cannot use the base verb go after am in this future tense structure.

29 with

– Why it's right: We use with to show that people are doing an activity together (watching it with friends).

– Why not 'by': We do not use by to talk about doing things together with other people; by is usually used for how you travel.

30 on

– Why it's right: We always use the preposition on before specific days of the week, like on Saturday morning.

– Why not 'at': We use at for the weekend or for exact clock times, but never for specific days of the week.

25 to

– Why it's right: We use to before a base verb to explain why we do an action. Noah is writing this message to tell his cousin something.

– Why not 'for': We can use for with a noun (like a message for you), but before a base verb like tell, we must always use to.

26 is

– Why it's right: We use there with the present simple verb is to say that one singular thing exists right now.

– Why not 'are': We use are for plural nouns, but a new tool is only one single thing, so the verb must be singular.

27 in / into

– Why it's right: We use the preposition in when we put something inside a closed space or a container, like a box or a folder.

– Why not 'on': We use on for flat surfaces, not for things that hold objects inside them.

28 because / as / since

– Why it's right: We use because to explain the reason why something is true. Getting lots of texts is the reason why the new tool is very useful.

– Why not 'but': The word but is used to show a difference or contrast, not to explain why something happens.

29 so

– Why it's right: We use so to link a reason with a result. Downloading the update is the reason, and being able to show him how to use it is the result.

– Why not 'because': The word because comes before a reason, but this gap needs a linking word that introduces the result.

30 you

– Why it's right: We need an object pronoun here. Noah is asking if his cousin wants to receive the action of helping, so we use you.

– Why not 'your': The word your is a possessive adjective used before a noun (like your phone), not an object pronoun used on its own.
