Reading — Expression of Ideas for the SAT Exam

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

• !Selecting a transition word that connects sentences logically but does not match the rhetorical relationship (concession vs contrast vs addition)
• !Choosing evidence that is merely related to the topic rather than specifically supporting the stated claim
• !Picking an answer that introduces a new idea instead of synthesising the notes or bullet points provided
• !Misidentifying whether the question asks for the 'most effective' introduction, body, or conclusion sentence

Study tips

• 1For transition questions, categorise transitions before selecting: addition (furthermore, moreover), contrast (however, nevertheless), cause/result (therefore, consequently), concession (although, while). Match the category to the relationship between the sentences.
• 2For rhetorical synthesis questions, the stem often says 'Using the notes above, the student wants to...' — read the goal statement carefully; it defines what counts as correct.
• 3Practise identifying the topic sentence and supporting details in short paragraphs. Expression of Ideas questions often ask which sentence best supports a given topic sentence.
• 4Do timed practice on the Expression of Ideas question type specifically — it is new to the Digital SAT format and requires different instincts than the old passage-based writing questions.

1. 1

   Choose the most effective transition to complete the sentence: 'The new drug showed promising results in lab trials. ______, it failed to produce the same effects in human clinical tests.'

   • AFurthermore,
   • BConsequently,
   • CHowever,Correct
   • DSimilarly,
   Why this answer?

   'However' signals a contrast between the promising lab results and the failed clinical results. 'Furthermore' and 'Similarly' would imply continuation or similarity. 'Consequently' would imply the clinical failure was caused by the lab results, which is not the logical relationship.

2. 2

   A student wants to argue that solar energy adoption has increased dramatically. Which evidence best supports this claim? Notes: (A) Solar panel efficiency was 15% in 2000. (B) Global solar capacity grew from 1 GW in 2000 to over 1,000 GW in 2022. (C) Wind energy is also growing rapidly. (D) Solar panels contain silicon.

   • ANote A
   • BNote BCorrect
   • CNote C
   • DNote D
   Why this answer?

   Note B directly supports the claim that adoption has 'increased dramatically' by providing specific quantitative data (1 GW to 1,000 GW). Note A discusses efficiency, not adoption; Note C discusses wind energy; Note D is factual background unrelated to the growth claim.
