Verbal Reasoning - Are you eagle-eyed enough to spot the bird?

1. (i) E
(ii) A
As birds with green wings sit together, then the two birds with blue wings must be sitting at one end. There is only one bird that has small grey feet, and this is the bird with a green body and wings and a red head. So, if this bird with the red head is sat on the left, then the two birds with blue wings must be sat at the other end (this gives you the answer to question (ii)). So, the bird in the middle must have a blue body and green wings (question (i)). Whether their feet are red or grey isn’t important although we know they are big!

2. (i) L
(ii) T
Drawing a diagram of where the children are placed, based on the clues, can help to visualise what is happening:

Neither Travis nor Lila can be in the north of the reserve as we are told they head down, leaving Nadia and Jenna there. Travis is south of Lila, so she must be on a central line: west, central or east.  As Nadia is in the northwest, Jenna must be at the northeast side since we are told they are at opposite ends in the north. Since nobody is south of Jenna, neither Lila nor Travis can be on this southwestern side. If Lila is to the west of Malcolm, and on the central line, she must be in the centre (question (i)). This puts Travis at the most southerly point (question (ii)).

Non-Verbal Reasoning - Can you discover which snail ate the strawberry?

Answer: Stella.
 
Follow the diagonals in this grid to understand the patterns.
 
The pattern inside the four triangles on the top line of the grid (at the top left and top right of the matrix) is made by ‘translating’ (combining) the shapes in the other three triangles on the same diagonal.
 
Rotation as well as translation is involved: the single line rotates 45 ° anticlockwise, the two connected lines rotate 90 ° clockwise. The small triangle rotates 180 ° (alternatively it can be seen to reflect). This triangle also swaps ‘colour’ with the triangle in the bottom grid opposite.
 
Once the shapes are combined, an arrow is created in the top right triangle pointing to the culprit, Stella!

The answer is paragraph 4, so the empty chair in the room with the concealed opening in the back wall is behind the locked door.
  • Paragraph 1 is incorrect because the door to the locked room opens the wrong way. We are told in the story that Mrs Fondlove rolls her weight ‘against a wooden door at the back of the hall’, so the door must open towards her. In answer paragraph 1, Flynn pushes the door open.
  • Paragraph 2 is incorrect because Mrs Fondlove is referred to as ‘a spinster’. A spinster is an unmarried woman, so this cannot be an accurate description of her.
  • Paragraph 3 describes Mrs Fondlove’s skirt as the same shade as her scarlet nostrils. In the passage, her skirt is described as ‘glaucous’, meaning a dull greyish green or blue colour. There is a clue to the meaning of ‘glaucous’ as we are told she has ‘similarly coloured hair’ and later in the story we learn that her hair is the same colour as the grey parrot.
  • Paragraph 5 is incorrect because of the context. In the passage are told that there is a colour television in the lounge. In answer paragraph 5 Flynn hears that a ‘regular post coach going past outside on a cobbled street with other horses passing. Horse-drawn carriages carrying the post were from Victorian times, being phased out in the 1850s, well before colour television!
