Word-Number Codes 4

The simplest way to check this (as you may have spotted) is that the end of CHOCOLATE is an anagram of TEA. None of the other possible Answers has the correct ...235 ending.
As it happens, in Answer 2, 0 was drafted-in to stand for H and 1 for L; 6 was not used at all

You can easily work out that PARIS has only 5 letters and must be represented by 75460. All of the four Answers contain the right number/letters; but only Answer 3 starts with 0, which must stand for S

Your easiest way in would probably either be to crack the double S in RUSSIAN and look for the telltale 3's in SPANISH (but none in ITALIAN, of course); or to match the rhyming suffixes on ITALIAN and RUSSIAN. ITALIAN has the two I's and A's in it (represented here by 6 and 1 respectively), and none of the other Answers then matches the target closely enough

Answer 3 spelt SPONGE (an animal, ultimately; and in that or synthetic form, more of a bathroom accessory than an edible vegetable or fruit); the others were BEANS, GRAPES and PEARS respectively.
Your best way to get started on this Question would be to look for the double-P in APPLES, or even more obviously, the repetition in BANANA (862626, here)

Answer 3 came out as VERBAL (wherever did that word spring from?): the others, in order, were TEA TREES, LEAVES and BRAMBLE.
Your starting-point for checking the coding would probably have been the E's in 2nd and 4th and final place in VEGETABLE, or perhaps the semi-mirror-image -ETA- / -ATTE- groups

Answer 3 very nearly spelt ICE SKATING, but we hadn't a code available for G, so the 3 (for 'F') was a close next-best but still wrong.
The others, in order, were: TENNIS, KARATE and CRICKET.
Once you had found the 7-letter FITNESS ending with its double S, the decoding should not have been unduly burdensome

The first three Answers were CORNET (a close cousin of the trumpet), HORN and CASTANETS; Answer 4 fairly obviously wanted to say TRIANGLE, but ran out of coded letters for G and L

The boss is CAPTAIN CLEMENT (Answer 2); the other phrases, in order, were METALLIC PAINT, MICE IN ATTIC and ALL CEMENT, TILE ETC

Answer 1 was correctly coded.
It would no doubt have helped further if we had been working in 'leet', and BABY had appeared as 8487 ... no such luck, alas!

The mistake was the misspelling of 'economist' as EKONOMIST, as the 3rd item in Answer 4 (since there was no C available and the word comes, in any case, from the Greek). This seems appropriate because the city ~ or originally, 'new town' ~ of Milton Keynes was so called after the surnames of two eminent economists, to wit Mr Milton and Mr Keynes (either of whom may, or may not, have been knighted in due course).
For reference, perhaps as you head onwards into more vocabulary-based Quizzes, the coded words were as follows:
Answer 1 : EMOTIONLESS, IMMENSITY ( = the quality of being huge ), INSOLENT, KILOTONNES (a large measure of mass, sometimes used to quantify the explosive equivalent of so-much TNT), KNOTTIEST and LISTLESSLY ( = in an unsettled manner)
Answer 2 : MISTOOK, MOISTEN, MOONLIT, MONOTONY (the quality of being dull), MISTLETOE and MOLTENNESS (the runny nature of very hot metal, perhaps after a major explosion or other heat-entailing event such as a volcanic eruption, or inside an industrial furnace)
Answer 3 : SYSTEM, SMOKILY (how a poorly-prepared fire might burn), SEMITONE (the minimum pitch interval between adjacent notes in Western music), SOMETIMES, SENSITISE (as in the making of something to be sensitive, e.g. sensitising a young child to music or danger) and SOLEMNITIES (the pomp and ritual of a major event such as a State Funeral)
Answer 4 : TONSILS (as in your throat, unless you've had them out), TOILETS (no comment), 'ekonomist' (see above), TENSION (tautness), TOKENISM (the sloppy attitude whereby an organisation takes on someone female / of colour, or of different body shape or mental or mobility status, or of some other supposed 'minority' ~ purely so other people will applaud them for doing the Politically Correct Thing, rather than on the actual relevant merits of the individual person), and finally TIMELESSNESS, the quality of a place or event where one is moved to 'stop and stare' and lose track of everyday passing time for as long as one feels one needs to appreciate the experience.

We hope this final Question was not a total time-stopper for you ... but if you can tackle a long, finicky multi-tasking code-based Question such as this, the simple 4- or 5-digit word codes in an 11+ Paper should be a breeze!
