Data and Decisions

In modern organisations, the (0) AVAILABILITY of reliable information has transformed the way decisions are made. Managers are no longer expected to rely purely on instinct; instead, they are encouraged to adopt a more (1) .......... (SYSTEM) approach to analysing evidence. This has led to a growing (2) .......... (AWARE) that data can reveal patterns which might otherwise remain hidden. However, numbers alone are rarely enough. Without careful (3) .......... (INTERPRET), even accurate figures can be misleading, and poor analysis may result in deeply (4) .......... (LOGIC) conclusions. Another challenge lies in the fact that not all data is equally useful. Some information is incomplete, while other sources may be of doubtful (5) .......... (RELY). For this reason, decision-makers must be willing to question both the origin and the quality of what they are given. In addition, the increasing (6) .......... (COMPLEX) of digital systems means that professionals need strong analytical skills and a high degree of (7) .......... (FLEXIBLE) when responding to new evidence. Ultimately, the most effective leaders are those who can combine technical knowledge with sound judgement and act with (8) .......... (CONFIDE) even in uncertain situations.

What to do

For each gap you get one word in capitals which you have to change so the grammar and meaning fit in the sentence. Here you have to show how well you know word families and if you can change words by using prefixes and suffixes.

You need to read the whole text to get the writer’s opinion on the topic. That’s because sometimes a negative prefix will be required. There is usually at least one word requiring a negative prefix, so look out for these.

In the exam always write something. You never know, you might be lucky even if you are not sure of the answer!

Strategy

  1. Read the title and the whole text so that you understand what it is about.
  2. Look at each sentence in detail.
  3. Think about what kind of word you need and whether you need a negative prefix or a suffix.
  4. Read the sentence again to check whether you need a plural form.
  5. Check your spelling, as it must be correct.
