Question

“sonnet 18”
shall i compare thee to a summer’s day?
thou art more lovely and more temperate:
rough winds do shake the darling buds of may,
and summer’s lease hath all too short a date:
sometime too hot the eye of heaven shines,
and often is his gold complexion dimm’d,
and every fair from fair sometime declines,
by chance, or nature’s changing course untrimm’d:
but thy eternal summer shall not fade,
nor lose possession of that fair thou ow’st,
nor shall death brag thou wander’st in his shade,
when in eternal lines to time thou grow’st,
so long as men can breathe or eyes can see,
so long lives this, and this gives life to thee.
read the line from “sonnet 18.”
rough winds do shake the darling buds of may
how many iambs are in the line?
five, because an iamb is an unstressed syllable and a stressed syllable.
five, because an iamb is a stressed syllable that is emphasized.
nine, because an iamb is the number of words found within a line of poetry.
ten, because an iamb is a count of the individual syllables in a poetic line.

Explanation:

Step1: Recall iamb definition

An iamb is a metrical foot with an unstressed syllable followed by a stressed syllable (e.g., \(\text{be - CAUSE}\), where "be" is unstressed and "CAUSE" is stressed).

Step2: Analyze the line "Rough winds do shake the darling buds of May"

Break the line into syllables and identify iambs:

• Rough (unstressed) winds (stressed) → 1st iamb
• do (unstressed) shake (stressed) → 2nd iamb
• the (unstressed) darling (stressed) → 3rd iamb
• buds (unstressed) of (stressed)? Wait, no, re - syllabify: Wait, let's do it properly. Let's split the line into syllables:
• Rough (1, unstressed)
• winds (2, stressed)
• do (3, unstressed)
• shake (4, stressed)
• the (5, unstressed)
• dar - (6, stressed, from darling: dar - ling)
• ling (7, unstressed? No, wait, "darling" is two syllables: dar (stressed) - ling (unstressed)? No, no, the stress in "darling" is on the first syllable: DAR - ling. So:
• Rough (unstressed) winds (stressed) → iamb 1
• do (unstressed) shake (stressed) → iamb 2
• the (unstressed) dar (stressed) → iamb 3
• ling (unstressed) buds (stressed)? No, wait, let's write the line with syllable stress:
• \(\text{rough}\) (unstressed) \(\text{winds}\) (stressed) / \(\text{do}\) (unstressed) \(\text{shake}\) (stressed) / \(\text{the}\) (unstressed) \(\text{dar}\) (stressed) / \(\text{ling}\) (unstressed) \(\text{buds}\) (stressed) / \(\text{of}\) (unstressed) \(\text{May}\) (stressed). Wait, no, that's not right. Wait, let's count the number of iambs. A Shakespearean sonnet is written in iambic pentameter, which has 5 iambs per line. Let's verify by splitting the line into iambs:
• (Rough) (winds) → no, wait, "Rough" is stressed? No, in normal pronunciation, "Rough" is stressed? Wait, no, the line is "Rough winds do shake the darling buds of May". Let's use the correct stress pattern for iambic pentameter. In iambic pentameter, each line has 10 syllables (5 iambs, each iamb has 2 syllables). Let's count the syllables:
• Rough (1)
• winds (2)
• do (3)
• shake (4)
• the (5)
• dar (6)
• ling (7)
• buds (8)
• of (9)
• May (10)

Now, group into iambs (unstressed - stressed):

• (Rough (unstressed) winds (stressed)) → 1
• (do (unstressed) shake (stressed)) → 2
• (the (unstressed) dar (stressed)) → 3
• (ling (unstressed) buds (stressed)) → 4? No, wait, "ling" is part of "darling", so "darling" is dar (stressed) - ling (unstressed). So maybe my initial syllabification was wrong. Let's use the standard iambic pentameter approach. A line in iambic pentameter has 5 iambs (10 syllables). Let's count the syllables in the line: "Rough winds do shake the darling buds of May" has 10 syllables (Rough, winds, do, shake, the, dar, ling, buds, of, May). Now, since an iamb is 2 syllables (unstressed + stressed), the number of iambs is \( \frac{10}{2}=5 \). Also, the first option correctly defines an iamb as an unstressed syllable followed by a stressed syllable. The other options are incorrect: the second option misdefines an iamb (an iamb is unstressed - stressed, not just a stressed syllable), the third option says an iamb is the number of words (wrong), the fourth option says an iamb is a count of individual syllables (wrong, an iamb is a metrical foot, not a count of syllables). So the correct reasoning is that an iamb is unstressed + stressed, and the line has 10 syllables (5 iambs).

Answer:

Five, because an iamb is an unstressed syllable and a stressed syllable.
