Compléter B2.4 Unit 9AVersion en ligne Past modals of deduction par Donis Leija Guerra 1 OK , so which pill do you think the spy ( might / choose ) ? 2 I think she ( may / grab ) the blue one . Red seems a dangerous colour to me . 3 The spy ( might / realise ) the situation was hopeless and not even cared if she was poisoned . 4 It still doesn ? t make sense . The guard ( couldn ? t / know ) which pill the spy was going to choose , so why would he take the risk of having to eat the other one ? 5 The guard ( may / plan ) to secretly swap whichever pill the spy chose for a poisoned one . 6 But the spy grabbed the pill so quickly , surely he ( couldn ? t / swap ) them . 7 I think that ? s too obvious . The colour ( could / be ) a red herring .
