[4th task last blank space "These"] The correct input should also be "There".
Before the blank space the concept of green spaces is being narrated in such way that the blank can contain both "These [are]" and "There [are]".
> "Green space [...] is experiencing a revival";
> this sentence ends, new sentence starts.
> "There are small green areas, parks or green islands created by taking up some space from the streets. " OR "These are small green areas, parks or green islands created by taking up some space from the streets. "
Both options fulfil the meaning of the sentence.
[5th task "be there in moments"] The correct input should be "be there in a moment's notice" or the task should be annulled.
"be there in moments" is not a valid phrase as no examples of such phrase can be found anywhere.
(see https://ludwig.guru/s/be+there+in+moments for text samples containing such phrase - there practically doesnt exist such text)
However, the phrase "be there in a moment's notice" is both comprehendable and viable for use in this task as all conditions are met, not counting the existence of the apostrophe.
[9th task "There is a lot of concern"] The correct input should be "There is concern to them"
Since one of the conditions for completing the task is to rewrite the given sentence while retaining its meaning, it is crucial to include in the sentence to whom it is concerning, thus it is important for the sentence to contain "to them". If this condition is not met, the task should not count as succesfully completed.
Moreover, the Oxford Languages defines "concern" as "anxiety; worry", which means that the answers "There is concern" and "There is a lot of concern", as well as the inclusion of similair adverbs (e.g., big concern; great concern, troubling concern etc.) would not impact the fact that the sentence retains the similar meaning.
[10th task "There is Some concern about"] The correct input should be "There is quite the concern to us about"
This task has a lot of common ground with the 9th task.
It should be a necessity to include to whom it is a concern (in this case, it is a concern "to us"). If that is not done, then an essential part of information is lost and the 2 sentences are not interchangable.
In this case the word "quite" is transferable from one sentence to another, so it only makes sense for the inlcusion of it to be a requirement.
[14th task "On no account can you"] The correct input should also be "On no account should you"
According to ludwig.guru (see https://ludwig.guru/s/on+no+account+should+you), the phrase "on no account should you" is also an acceptable option used in the English language. Since both phrases are interchangeable, same should apply to this task.
[15th task "Despite all her problems"] The clause can end with a comma; the correct input should also be "Despite having lots of problems, "
Introductory clauses are always separated with a comma, but if the clause is short enough, the comma can be ommited for stylistic purpoises
(see https://www.grammarly.com/blog/commas-after-introductory-clauses/).
Since the main clause of the sentence already contains the word "her", the introductory clause does not require the use of the pronoun, thus validating "Despite having lots of problems, " as a correct input.
[17th task "We are very grateful for all"] the correct input should also be "We are grateful for"
Although the supposedly correct input does show more respect and gratefullness than the newly proposed one, the Oxford Languages define "grateful" as "feeling or showing an appreciation for something done or received", thus the inlcusion of this word without additional "ornamental words" is enough for the sentence to express gratitude and fulfill the necessary conditions.
According to ludwig.guru (see https://ludwig.guru/s/grateful+for+your+work) The sentence "We are grateful for your work." is valid without the inclusion of the word "all".
[19th task "It is recommended that you visit"] the correct input should also be "It is recommended to visit"
Since the second clause of the sentence already contains the pronoun "you", this pronoun can be ommited in the first one, thus validating "It is recommended to visit" as a correct input.
[20th task "It was as clear as mud"] The correct input should be "It was as clear as mud to me"
It should be a necessity to include to whom it "was as clear as mud" (in this case, it is as clear as mud "to me"). If that is not done, then an essential part of information is lost and the 2 sentences are not interchangable.
[23rd task "ring a bell"] The correct input should also be "ring a bell to you"
A language forum (see https://forum.wordreference.com/threads/does-it-ring-a-bell-with-you.28625/) suggests that English-speaking people use both "ring a bell", "ring a bell to someone", and "ring a bell with someone" interchangeably, hence all 3 options should be accepted.
[24th task " wish I hadn’t gone to"] "hadn’t" contains an unusual apostrophe
Many people type on their computers with ----> ' <---- as the apostrophe. because of this, many students did not have their otherwise correct input accepted in this task.
[26th task statement 1 "NOT GIVEN"] The correct answer should be "FALSE"
Information is in fact given.
The statement in question was "NHS warns against issuing antidepressants to adolescents under 18 for anxiety and depression".
The first statement contradicts with the contents of the first paragraph: "Health service guidance says that they [antidepressants] should be offered to under-18s only in cases of moderate or severe depression alongside talking therapies."
> The 1st statement states that NHS warns against issuing antidepressants to under-18s
> The text states that NHS recommends issuing antidepressants to under-18s only on the condition of having moderate or severe mental issues.
Since the 1st statement contradicts with the given text (the NHS is not against the use of antidepressants, but instead is against the use of it only when the need for such drugs is not dire), the statement is "FALSE".
[26th task statement 4 "NOT GIVEN"] The correct answer should be "FALSE"
Information is in fact given.
The statement in question was " Antidepressants can replace talking therapies when anxiety or depression is severe."
The first statement contradicts with the contents of the first paragraph: "Health service guidance says that they [antidepressants] should be offered to under-18s only in cases of moderate or severe depression alongside talking therapies."
Since antidepressants should only be prescribed alongside talking therapies, it can be deducted that antidepressants should not be prescribed without talking therapies, or, to rephrase, antidepressants cannot replace talking therapies when anxiety or depression is severe.
> The 4th statement states that antidepressants can replace talking therapies when anxiety or depression is severe
> The text states that antidepressants cannot replace talking therapies when anxiety or depression is severe
For this reason the 4th statement is "FALSE".
