Cambridge 11 Test 4 ranges across genetics, cinema and language. Passage 1, Research using twins, explains how identical and fraternal twins help researchers separate the effects of nature from nurture. Passage 2, An Introduction to Film Sound, argues that the soundtrack is as carefully constructed as the image. Passage 3, This Marvellous Invention, celebrates language as humanity's most consequential creation.
The opening passage carries four True/False/Not Given, five matching items linking researchers to claims and a four-gap summary — the matching block rewards distinctive names, so start with the rarest. Passage 2 mixes five multiple choice, five True/False/Not Given and three classifying questions on sound categories. Passage 3 finishes with six headings, a four-gap summary and four Yes/No/Not Given items where the author's enthusiasm for language is strong; make sure you separate his views from accepted facts.
Allow seventeen minutes on twins, eighteen on film sound, twenty-five on language, with two minutes for transfer. The headings task in Passage 3 is the highest-value single block, so do not rush it. Identical twins share their DNA — this paper shares its difficulty unequally, with the heaviest demands on Passage 3.
