• The first in the sequence should be the one that introduces us to the theme of the passage. Here, the passage is about why large companies hire trained psychologists. Thus, A will be the first sequence.
  
  
• D will be the next in the sequence as it mentions the job undertaken by the trained psychologists mentioned in previous sentence A.
  
  
• C will be the next as it mentions the act of taking inputs from senior managers by psychologists for designing competency models (mentioned in previous sentence D).
  
  
• B will be the final sentence of the sequence as it concludes by adding that psychologists develop similar models for lower ranks in the company.

Thus, the correct sequence is ADCB.

After rearranging the sentences, the passage will be: - Most large companies these days employ trained psychologists. Their job is to develop 'competency models' to aid the companies in identifying, training, and promoting likely managers who could take on leadership roles. To create these competency models, the psychologists ask senior managers to identify the capabilities that are typically needed for such roles. Later, the psychologists also develop such models for lower-level positions in the company.

Hence, option C is the correct answer.

* The first in the sequence should be the one that introduces us to the theme of the passage. Here, the passage is about unexpected encounter between Mrs. Salmon and Adams. Thus, A will be the first sequence.

* D will be the next in the sequence as it mentions the sound of a door click shut and false perception by Mrs. Salmon about its origin i.e. it is coming from her door.

* C will be the next as it mentions what Mrs. Salmon saw when she went towards her window to ascertain what caused that sound of a door click shut (mentioned in previous sentence D).

* B will be the final sentence of the sequence as it concludes by describing what Adams (introduced in Sentence C) was carrying and doing in front of Mrs. Parker's house.

Thus, the correct sequence is ADCB.

After arranging the sentences, the passage will be: - Mrs. Salmon who lived in 15, Northwood Street had been unable to sleep. She heard a door click shut and thought it was her own gate. But when she went to the window she saw Adams standing on the steps of Mrs. Parker's house. He had a hammer in his hand and had just come out of her house.

Hence, option B is the correct answer.

• The first in the sequence should be the one that introduces us to the theme of the passage. Here, the passage is about a Puller who strolled mentally through Fort Leavenworth. Thus, A will be the first sequence.
  
  
• B will be the next in the sequence as it mentions Puller’s mental trip to Fort Leavenworth after closing his eyes (mentioned in Sentence A).
  
  
• D will be the next as it mentions that he kept on strolling in his mind until he finds an answer.
  
  
• C will be the final sentence of the sequence as it concludes by mentioning the final act of ending his mental trip by opening his eyes. 

Thus, the correct sequence is ABDC.

After rearranging the sentences, the passage will be: Puller sat back and closed his eyes. In his mind's eye he took a trip through Fort Leavenworth, a place he had often been to in his career. His photographic memory clicking away, Puller kept up his mental scroll until he came to the answer. He opened his eyes.

Hence, option A is the correct answer.

• The first in the sequence should be the one that introduces us to the theme of the passage. Here, the passage is about the Impact of choices in our life. Thus, A will be the first sequence.
• C will be the next in the sequence as it mentions the effect of “choices” mentioned in previous sentence A.
• B will be the next as it mentions one of the choices i.e. “living on the edge”.
• D will be the final sentence of the sequence as it concludes by mentioning that following limits always leads to a better and safer life. Also, it uses the word “therefore” which shows the given sentence is the part of a conclusion that is always put at the end of a passage.

Thus, the correct sequence is ACBD.

After rearranging the sentences, the passage will be: We make a lot of choices in our daily life. These determine either our safety or put us in danger. Living on the edge may be exciting but not always the right thing to do. Therefore, following limits is always the safer and better way of life.

Hence, option A is the correct answer.

• The first in the sequence should be the one that introduces us to the theme of the passage. Here, the passage is about two ways of getting rid of weeds in the garden. Thus, A is the first sequence.
  
  
• B will be the next in the sequence as it mentions the first way i.e. “easy way” introduced in sentence A.
  
  
• D will be the next as it mentions the second way i.e. “not-so-easy way”.
  
  
• C will be the final sentence of the sequence as it concludes by mentioning that the second way is the better way to get rid of weeds for a longer duration.

Thus, the correct sequence is ABDC.

After rearranging the sentences, the passage will be: - There are two ways of getting rid of weeds in your garden - the easy way and the not-so-easy way. The easy way may be to run a lawn-mower and the lawn looks fine for a while. But the not-so-easy way may mean getting down on your knees and pulling out the weeds by the roots. It is time consuming and painful, but the weeds will stay away for a longer time.

Hence, option B is the correct answer.

• The sentence should begin with part Q as it introduces the subject of the sentence i.e. ‘almonds’.
  
  
• Next in the sequence will be R, which introduces us to an idea different from what has just been said in Q. 
  
  
• S will come next in the sequence followed by P which has the relative pronoun "that" used for "tree".

Hence, option B is the correct answer. 

• The sentence should begin with the segment S as it introduces the subject of the sentence.

• Out of the given options, only option d contains S as the starting segment.

• Thus, the correct sequence is SQRP.
  

• The sentence should begin with segment R as it introduces the subject of the sentence i.e. ‘autumn’.
  
• The next segment should be P as it tells what happens during the autumn season.

• P should be followed with S which states that the summer temperature decreases to cold winter which is mentioned in the sentence Q.

• Thus, the sequence should be RPSQ.

• The word ‘much’ in P precedes article ‘a’. It means ‘much’ acts as a determiner and needs a noun after it. So, we cannot end the sentence with P. P will be followed by Q. 
  
  
• The noun "trees" and its connection with "European forests" is evident. Thus, R should be first in the sequence. 

• The word that fits after the adjective "convincing" is "arguments" and no other word can fit here.
  
  
• R follows P as it states against whom the arguments were made.
  
  
• Q completes the sentence.
