Q.4 All engineering students I should learn II mechanics, mathematics and how to do III computation IV.

Which of the above underlined parts of the sentence is not appropriate?

• (A) I
• (B) II
• (C) III
• (D) IV
  

  Correct Answer

  The not appropriate part is (D) IV.

  Detailed Explanation

  The sentence is: “All engineering students I should learn II mechanics, mathematics and how to do III computation IV.” Based on standard exam formats (e.g., GATE-style questions), the underlined parts are:

  • I: “should learn” (inverted word order).

  • II: “mechanics” (first list item).

  • III: “how to do” (intro to third item).

  • IV: “computation” (third item).

  The error is parallelism in the list: “should learn mechanics, mathematics and how to do computation.” Items must match structure (nouns: mechanics, mathematics, computation). “How to do computation” breaks symmetry—should be just “computation” (computing/science subject).​

  • (A) I (“should learn”): Appropriate. Modal “should” + base verb is correct for advice to “all” (group as singular).​

  • (B) II (“mechanics”): Appropriate. Noun phrase; fits parallel list start.

  • (C) III (“how to do”): Appropriate in position, but enables IV error. Retains “and”; no solo issue.

  • (D) IV (“computation”): Not appropriate. Third item “how to do computation” mismatches nouns. Fix: “mechanics, mathematics, and computation” for uniformity.

  Key Grammar Rule: Parallel structure in lists—consistent form (all nouns here). Avoid mixing noun + infinitive phrase.

  Corrected Sentence: “All engineering students should learn mechanics, mathematics, and computation.”

  Introduction to Engineering Students Grammar Error

  Confused by “All engineering students underlined parts” questions? This tests spotting inappropriate parts in: “All engineering students I should learn II mechanics, mathematics and how to do III computation IV.” Options (A) I, (B) II, (C) III, (D) IV—one disrupts flow. Crucial for GATE, competitive exams—master parallelism today!

  Parallelism Rule: Why Lists Fail in Engineering Sentences

  Lists demand parallel structure: matching grammar (e.g., all nouns: mechanics, mathematics, computation). Here, “how to do computation” mixes noun phrase with infinitive—breaks symmetry.

  Every Option Explained: Spot the Inappropriate Part

  Detailed verdict on engineering students underlined parts:

  Option	Part	Why Appropriate/Inappropriate?	Fix Needed?
  (A) I	“should learn”	Correct modal + verb for group advice.	No​.
  (B) II	“mechanics”	Proper noun; starts parallel list.	No.
  (C) III	“how to do”	Links third item; “and” fits.	No (enables IV issue).
  (D) IV	“computation”	Inappropriate—full “how to do computation” mismatches nouns.	Change to “computation”.

  Full Sentence Breakdown and Correction

  • Original Issue: Third item verbose, destroys uniformity.

  • Fixed: “All engineering students should learn mechanics, mathematics, and computation.” (All subjects.)​

  Parallelism Examples:

  • Good: “Learn physics, chemistry, and biology.”

  • Bad: “Learn physics, chemistry, and how to do biology.”

  Why IV is the Error: GATE-Style Insights

  In exams, IV holds “computation” but flags the awkward phrase it completes. “Computation” parallels “mechanics/mathematics” (engineering fields).

  Exam Strategies for Underlined Parts Questions

  • Check lists for matching forms.

  • Ignore I/II if structure OK.

  • Test: Read aloud—awkward? Error!

  • Practice: 80% GATE aptitude hits parallelism.

  Pro Tip: Engineering curricula stress mechanics, mathematics, computation—fits corrected version.
